Pokémon Trading Card Game/Lightning Club

The Lightning Club members primarily use Lightning type Pokémon. Lightning type Pokémon use strong attacks with high energy costs that either discard their Energy cards after use, or have a change of damaging themselves as part of the attack.

Jennifer
Jennifer's deck's gimmick is right in the name. It's full of Pikachu cards, including Surfing Pikachu and Flying Pikachu. Everything other than Flying Pikachu is weak to Fighting type Pokémon. That does pose a problem with Flying Pikachu though, as it has resistance to Fighting so damage from Pokémon of that type is massively reduced. Make sure you have some Colorless Pokémon, Pokémon of another type, or a Pokémon that damages the bench instead to deal with it. Remember that attacks that damage the benched Pokémon are not affected by weakness or resistance so it's more efficient to damage a benched Flying Pikachu over other choices.

Brandon
This deck has just about every Lightning Pokémon in the game and a large amount of energy. There isn't much of a strategy behind this deck. It's a purely aggressive, attack every turn starting from the first turn, aggro deck. Once again, if you've chosen Fighting type Pokémon for your deck you need to watch out for Zapdos. It is resistant instead of weak to Fighting type Pokémon. Fighting around it to hit the bench isn't as effective as against Flying Pikachu. Once it gets powered up it is very powerful, and there will be higher HP values on the bench than the Pikachus had.

Nicholas
The goal of Nicholas' deck is to evolve his Pokémon and use their powerful Selfdestruct attacks to wipe out both active Pokémon and damage the benches. If he gets lucky, he'll have enough Defender trainer cards to attach to his Pokémon to keep them from getting knocked out. In your favor is that he has chosen three different evolution lines to accomplish this, each of separate types. This makes it difficult for him to get his Pokémon evolved and powered up quickly enough to overwhelm you.

Club Master: Isaac
Before Isaac will bother accepting a challenge from you, you'll have to defeat all three of the other members.

His strategy is a more refined version of Nicholas' strategy. Magnemite and Magneton will Selfdestruct to deal massive damage to your active Pokémon and both benches. Tauros takes advantage of getting damaged on the bench to deal more damage when he comes into the active spot. Rampage does 10 more damage for each damage counter on Tauros. That's 70 damage at its strongest. Luckily you should be able to knock it out quickly in response since at that point it only has 10 HP left.

Kangaskhan will draw him more cards if he's low on any resources. Its Comet Punch is a little bit scary because it does a lot of damage, but since it's coin flip based you can get lucky and not get hit. Electrode will hit through resistance and power up other Pokémon on the bench. Electabuzz and Magnemite can also stall by causing Paralysis on a coin flip. Otherwise, all of his Pokémon are weak to Fighting with no tricks like Flying Pikachu or Zapdos to worry about.

Promo Electabuzz
In the lounge there is a Chap offering a trade. He wants an Electabuzz from the Colosseum pack and is offering a promotional Electabuzz. Since this club's booster packs will bias towards including Lightning and Colorless Pokémon in them, you can face Brandon and Nicholas several times to see if you can win one to trade. The normal Electabuzz is also such a powerful card, you might want to grind out a few duels for several to use for your own decks.
