Pokémon Trading Card Game/Water Club

The Water Club is one of the clubs were members use decks almost purely of their signature type. This is bolstered by the fact that there are more Water type Pokémon cards at this point in time in the TCG than any other type, and because some Water type Pokémon cards are weak to Grass, while others are weak to Lightning.

The Bulbasuar & Friends Deck may fair decently here, but without Lightning type Pokémon it really depends on the luck of the draw of your opponent.

Sara
This is one of the few characters in the game that sets the prizes so low. Due to this, you can try to rely on your luck that Sara will play a couple of Pokémon that you can knock out quickly and easily for some easy wins.

Amanda
Amanda's Water type Pokémon are all weak to Grass, and even one of her supporting Pokémon, Aerodactyl, is also weak to Grass. This makes here the easiest target for a Bulbasaur & Friends Deck player.

Joshua
Joshua refuses to duel you unless you have beaten both Sara and Amanda.

Club Master: Amy
Once you've defeated Joshua, and therefore all of the other club members, he will let you face Amy in a duel.

Arcanine Promo
In the lounge, over by the card table is a Gal who wants to trade away an Arcanine card for a Lapras card. This Arcanine card is a promotional card, but you can also earn it later in the game at one of the set Challenge Cups at the ../Challenge Hall/. It might be a good idea to hold onto your Lapras card being as it is a rare unless you have them in abundance.

Imakuni?
When you talk to the Lass in the lounge of the club, she'll talk about ../Imakuni?/ and this will trigger him to start appearing in club lounges.
