Wishiwashi ex is the deck's main attacker, being able to deal devastating damage if the Bench is filled with Wishiwashi and Wishiwashi ex. It is paired with Manaphy in this deck for Energy acceleration.
Manaphy is not compatible with School Storm. However, it can be useful to return it to your hand with the Fishing Net once it is knocked out. You may use Pokemon Communication to return Manaphy to your deck for a chance to draw a Wishiwashi.

School Storm deals 150 damage with a full Bench of Wishiwashi and Wishiwashi ex. It may help to use cards that can help you draw the cards that you need, such as Poke Ball, Professor's Research, and Iono..

Wishiwashi has a low HP of 30, making it easy to knock out. You may return it to your hand with the Fishing Net in order to place it onto your Bench.


Wishiwashi ex has a relatively high Attack Cost. You may use Misty in order to give it a chance to attack immediately. Manaphy is another option, but keep in mind that it doesn't synergize well with School Storm.


Lightning-type decks that do not require much setup can be effective in dealing with Wishiwashi ex decks. In addition to the type advantage, they can also attack much quicker due to a lower Attack Cost, which may allow them to secure KOs.
Best Lightning Type Deck and Cards Tier List



Wishiwashi only has 30 HP, so it is easy to knock it out and decrease Wishiwashi ex's damage. Sabrina and Cyrus can draw it out to the Active Spot. You can also use cards that can damage Benched Pokemon such as Genetic Apex Hitmonlee.
