Whiscash Mill (June 2023)

 Using the Swovet/Koraidon ex/Revavroom engine, which is using swovet's ability to get one card in your hand, Revavrooms ability to get energy into the discard pile and get your hand pack to 6 cards. You could also use it with Radiant Greninja. Then use Koraidon's ability to power up the Whiscash on your bench. Do all of this with Great tusk in your active spot (it can take multiple hits and gives you time to power it up) and can be used as a secondary attacker. Then switch your Whiscash into the active spot using excape rope. Attack and discard up to 26 cards from their deck at a time! After 3 or 4 turns used as a secondary attacker. If the wishcash doesn't get knocked out, your opponent will deck out.
