Acro Bike Clay Hapu Ingo & Emmet Jessie & James Milo Oleana Professor's Research Quick Ball TAG TEAM Supporters I left off pre-TEU cards like Mysterious Treasure as - for us - it will likely only be Standard-legal alongside "Mad Party" cards for a very short time, if at all. As Professor's Research and Quick Ball are staples in general, I'm guessing they were supposed to be givens. I know, I know... few of these are probably going to be worthwhile, though I think Clay might have some potential if there was a way to get all your Twin Energy out of your deck before hand. Or to recycle them, preferably via Item card. Note: This is not me saying that Mad Party will be a good deck, either in Standard, Expanded, or Yaginku's Single-Prize Only Format. His comment just got me wondering what other tricks one might use to discard said Pokémon in a post-TEU cardpool, and I figured I may as well share my list.
