'Tasha' cards

Whenever you cast a spell you don't own, create a 3/3 black Demon creature token. +1: Draw a card. For each opponent, exile up to one target instant or sorcery card from that player's graveyard and put a page counter on it. -3: You may cast a spell from among cards in exile with page counters on them without paying its mana cost. Tasha, the Witch Queen can be your commander.

+1: Until your next turn, whenever a creature attacks you or Tasha, Unholy Archmage, put a -1/-1 counter on that creature. -2: Target opponent puts a creature card of their choice from their graveyard onto the battlefield under your control. That creature gains ward {2}. -6: Target opponent reveals cards from the top of their library until they reveal three creature cards. Put those cards onto the battlefield under your control. That player puts the rest into their graveyard.
