I've removed extra attacking options, palkia v star and trainer cards that add complicated combos and opted for cards that provide the deck with maximum consistency in being able to pull off 3 things.
1. set up turn 1, going first or second you have options with irida, celebrations mew to find vip or ball search, and squawkabilly ex if you completely fail your opening hand. Also ultra ball for lumineon for irida for setup and v I p pass, only use this if ur hand isn't garbage and you want to keep combo pieces.
2. Set up baxcalibur for energy acceleration for the rest of the game. Celebrations mew can find ultra ball for arceus or rare candy for baxcalibur, pokegear for irida. Irida gets you pieces, either baxcalibur evolution line, or arceus for the missing pieces. Ultra ball can get you lumineon for irida ~> for arceus and an item, giving you 3 pieces with star birth. or ultra ball for arceus giving you 2 pieces.
3. Boss orders cancelling cologne play with radiant greninja. Late game Celebrations mew can find you the cologne, or pokegear for boss. Arceus can get you the boss and cologne. Or combine mew and arceus can get you 3 pieces for this combo.
