Catch Pokémon — 1, Tap: Reveal the top card of your library. If it is a creature card, you may exile it. Then, roll a six-sided die. On a roll of 6, put the exiled creature onto the battlefield under your control. On a roll of 1-5, put the exiled card on the bottom of your library. If you put a creature card onto the battlefield this way, sacrifice Poké Ball. If the creature shares a type with you commander, you need to roll a 4-6 instead of a 6
