Pokkén Tournament/Cheers and Supports

Even before the battle commences, there are a few strategic choices every player must make. These are your Cheer Skills and Support Pokemon. They offer a range of helpful enhancements that you can use to round out your playstyle, or to better handle certain matchups. In the Ferrum League and online matchmaking, you only get to choose between three pairs of Support Pokemon and a single Cheer Skill, which you have to set beforehand in your profile. However, you are free to choose from the full range of unlocked Cheer Skills and Support Pokemon in local matches.

Cheer Skills
Nia the in-game advisor doesn't just provide helpful tips about the game, but also give you various bonuses at the start of the match! Cheer Skills focus only on your Synergy Gauge and Support Gauge, adding to them each round depending on the type of Cheer Skill you select.

Standard
This Cheer Skill only comes into effect from the second round onward. Winning the previous round maxes the Support Gauge for the Support Pokemon you didn't use the last round. Losing the previous round maxes both Support Pokemon as well give you an increase in Synergy. It's very uncommon for both Support Pokemon in a pair to be suitable in one matchup, so the winning bonus is not very attractive. The Support Focused cheer is almost a direct upgrade save for the Synergy increase you get when you lose.

Synergy Focused
Your Synergy Gauge gets a minor increase every round. This cheer skill's effects are minor but consistent, building up small chunks of your Synergy every round. It is important to note that Synergy only matters if you manage to fill the gauge completely, so if you have trouble getting Synergy Burst even with the cheer skill, you're better off selecting another cheer. Usually helpful for characters with slower charging Synergy Gauges, less so for fighters that build meter so fast that the cheer's boost is negligible.

Pressure Focused
You will get a huge bonus to your Synergy Gauge only on the third round regardless of whether you won or lost the previous round. This cheer is used to give you an edge during the deciding round of a match, but has no effect otherwise. The large Synergy boost benefits slow-charging Synergy characters like Gengar that can really turn the tides once they enter Synergy Burst. The main issue with this cheer is you'd ideally want a buff that helps you win the first two rounds without risking it all on the last round, and if you can already achieve that this cheer skill is effectively useless.

Support Focused
From the second round onward, both of your Support Pokemon get maxed gauges. A popular cheer since it has a useful and versatile effect no matter the situation. Compared to Synergy-based cheers where the end goal is to enter Synergy Burst, this cheer can have varying effects on the tide of battle depending on what Support Pokemon you're using. For quick charging Supports, it will let you squeeze one more use out of their Support skill. For slow charging Supports, it will let you have access to their powerful effects from the start of the round, which you can save for the right opportunity to unleash them.

Special
From the second round onward, winning the previous round gives you a small amount of Synergy Gauge while losing maxes out both Support Pokemon gauges. This cheer is like a mix between the Synergy Focused and Support Focused cheers, giving you buffs to different gauges depending on the results on the previous match. As you can't really control what results you'll get and thus the rewards you'll be given, try to decide whether you need Synergy or Support more and focus solely on that one aspect with either of the aforementioned cheers. Either benefit of the Special cheer have their uses, generally one is not inherently better than the other.

Whimsical
Every round gives a random effect. Either Support Pokemon can get maxed gauges and you may get a random amount of Synergy Gauge as well. There is also a likelihood of getting nothing at all, so it all comes down to luck. Due to the unpredictability of this cheer, it is never the optimal cheer skill for any matchup and thus can't be recommended as a strategic choice. However, it can potentially give the greatest reward of any cheer skill, so if you're in the mood to gamble, it could be an interesting cheer to try.

Support Pokemon
Support Pokemon come in pairs, each of which have their own effects. A pair of supports usually share a strategic or thematic similarity, and you can choose to use either Pokemon as your support at the beginning of each round. Each support has a different charge rate and occasionally recharge rate, though certain characters can increase the Support Gauge to make them available faster. It's common to pick a Support Pokemon set just for a singular support Pokemon, for instance, the Cresselia and Reshiram set is often chosen solely for Cresselia while Reshiram is typically neglected.

Emolga - Shock Wave
Emolga fires an electric beam at the opponent, inflicting a speed debuff in addition to dealing damage. This is an extremely versatile and spammable support favored by both long-distance zoners and close combatants alike. The attack has incredible range and travels almost instantaneously. It knocks the foe down upon hit and pierces counters. Zoning characters use it to supplement their own projectiles and to stuff CADC approaches with Emolga's counter pierce property, while using the slow debuff to impede further advances. For close-range fighters, they appreciate having a long-range attack of their own and can make use of the knockdown and slow to close in on a foe.
 * 30s charge time

Fennekin - Ember
Fennekin creates an expanding fireball around the user. This support is a mainly defensive one. It grants you invulnerability at the start of the attack and hits in every direction around you. It has a bit of startup that foes can react to, but blocking the attack pushes them far enough to keep you safe after the move ends. While not a bad support itself, Fennekin is overshadowed by Umbreon as a defensive support due to the latter's versatility and speed.
 * 30s charge time, 40s recharge time

Snivy - Leaf Tornado
Snivy creates a tornado that homes in on the opponent. It causes a knockdown on grounded foes but juggles aerial ones. Snivy is a support that can be adapted for many situations, capable of performing several roles when needed. The most obvious use it is designed for is as an anti-air, being tall enough to suck in airborne foes and letting you combo out of it afterward. It is also good for projectile pressure, locking down guarding foes in blockstun and going through counters. Snivy's usefulness mainly comes from its short charge time, making it available for use often during the match.
 * 20s charge time

Lapras - Surf
Lapras charges forward at its foe, shielding the user against most projectiles while it does so. A decent support that is mainly used to eat up projectiles. It doesn't move very fast, so you can use it to cover your approach. It is also used in combos because it causes and extends wall splats, letting you pull off damaging wall combos.
 * 30s charge time, 40s recharge time

Frogadier - Water Pulse
Frogadier fires water blasts in 2 volleys of 3 shots, having a slight delay between volleys. This support is excellent for pressure due to its quick charge rate and attack pattern. Frogadier jumps before launching its projectiles, and it has very good aim, so it is difficult to simply evade its shots. It also lets you attack in tandem with it to rack on the pressure, or to combo out of or into its attacks. A basic but effective mixup is to grab during the pause between volleys, since your foe can get hit by Frogadier if they drop their guard to break your grab.
 * 20s charge time

Eevee - Helping Hand
Eevee grants the user a moderately short Attack buff and a small amount of recoverable HP. The benefits of an Attack buff is quite obvious: increasing your damage means defeating the foe with fewer hits. However, there is an additional hidden trait of the Attack buff, that is, it cancels out the light attack armor fighters get in Synergy Burst! This makes Eevee more of a matchup-specific support, as it can be very handy against quick Synergy charging characters like Pikachu Libre.
 * 20s charge time, 40s recharge time

Cubone & Diglett
Unlocked by clearing the Green League Promotion Test

Cubone - Bonemerang
Cubone tosses a giant bone projectile that flies forward and returns to it after traveling a certain distance. This support is designed to fit well in to combos, having very low startup, putting the foe in a spinning state on hit and being able to potentially connect twice in a combo. Its quick charge rate gives you more opportunities to increase your combo damage with Cubone. Being a quick, wide projectile, the bonemerang can also be used to stuff approaches or as a long-range punish.
 * 20s charge time, 30s recharge time

Diglett - Dig
Diglett tunnels through the ground, homing in at the foe. In Field Phase, it rapidly juts out of the ground below the opponent, putting them into an extended juggle. In Duel Phase, it does a single burst out of the ground with a large radius and height that launches enemies skyward. In either case, Diglett's attack is either made to start combos or extend them, excelling at juggle combos while Cubone complements ground combos. Its not too great as a raw attack since Diglett's homing speed is pretty low, but it does let you follow behind it to pressure your foe.
 * 30s charge time, 20s recharge time

Jirachi & Whimsicott
Unlocked by clearing the Green League Promotion Test

Jirachi - Wish
Jirachi provides a moderate Synergy increase and grants the user a Synergy Burst buff, which increases attack and defense only during Synergy Burst mode. This support is a favorite of fast-charging Synergy characters since they can make use of Jirachi much more often. The Synergy Burst buff is particularly powerful, since it stacks with the universal stat augmentations that comes with Synergy Burst as well as other status buffs like a separate Defense buff, which can result in ridiculous total stat increases during burst mode. Unfortunately, Jirachi's effect is useless if you're nowhere close to a full Synergy Gauge, making it unpopular for slow Synergy building characters.
 * 30s charge time, 40s recharge time

Whimsicott - Substitute
Whimsicott creates a barrier around the user that shields them from projectiles, as well as heal some recoverable HP. This is naturally a great support against zoning characters, since it nullifies most projectiles that touches you, letting you approach without worrying about enemy ranged attacks. Beams are a special case as they can still go through the barrier, so be careful against characters that have it. While it has a similar effect to Pachirisu, Whimsicott has a faster charge time, longer duration and a heal, but can't nullify as many types of projectiles as Pachirisu.
 * 30s charge time

Croagunk & Sylveon
Unlocked by clearing the Green League Promotion Test

Croagunk - Toxic
Croagunk creates a ring around itself. Any foes that enter the ring gets hit by a poisonous attack that reduces Defense. This support is naturally a strong space control tool, especially in Duel Phase where it can cover a relatively larger fraction of the stage. It can be used to protect yourself, guarding you against all close-range assault, or to pressure the foe if you can pin them close to the wall. The Defense debuff causes enemies to take more damage, an obviously beneficial debuff to you.
 * 20s charge time, 30s recharge time

Sylveon - Reflect
Sylveon heals a bit of HP and grants a Defense Up buff. Increasing Defense not only makes you take less damage from enemy attacks, but also enables your shield to take more punishment. As far as supports go, Sylveon is very straightforward, but it doesn't help you approach, pressure or escape outside of making your mistakes less punishing. It is typically used by characters with a lot of HP like Machamp against specific zoning matchups, as they have enough HP to abuse the increased defense and appreciates it when approaching against projectiles.
 * 20s charge time, 40s recharge time

Pachirisu & Magikarp
Unlocked by clearing the Blue League Promotion Test

Pachirisu - Follow Me
Pachirisu draws all enemy projectiles to itself, completely negating them. When Follow Me is active, most projectiles will simply fail to appear, with the exception of beam attacks. Compared to Whimsicott, which also has a projectile-canceling effect, Pachirisu's takes longer to be available and has a more brief effect, but it can absorb a greater variety of projectiles, which notably includes numerous other Support Pokemon.
 * 40s charge time

Magikarp - Bounce
Magikarp launches into the sky, targeting the enemy. If the user gets hit, it will drop back down and hit the foe. The effect disappears after a while or if either player causes a phase shift. Magikarp functions as a combo breaker, a defensive tool that prevents foes from punishing your mistakes with big combos, drastically lowering the damage they can do to you. Since Magikarp's effect is such a strong defensive ability, it compensates with a very lengthy charge time that limits its usefulness. However, it has a fairly fast recharge rate after being used the first time, which can be exploited with certain cheer skills that fill the Support Gauge early.
 * 50s charge time, 20s recharge time
