Gain control of target nonland permanent an opponent controls. Its owner reveals cards from the top of their library until they reveal a card that shares a type with that permanent, then puts it onto the battlefield and shuffles.

Whenever you activate a nonmana ability of a permanent during your turn, you may choose one that hasn't been chosen yet this turn —
• That permanent becomes a 3/3 Dragon creature with flying in addition to its other types until end of turn.
• Each opponent discards a card and loses 2 life.
• Copy that ability. You may choose new targets for the copy.

Prowess, trample
During your turn, each instant and sorcery card in your graveyard has flashback. The flashback cost is equal to that card's mana cost plus “Pay X life, where X is this card's mana value.”

Flying

Flying
Whenever one or more creatures you control deal combat damage to a player, exile the top card of that player's library. Until end of turn, you may play cards exiled with Zorganis, Dread Specter and you may spend mana as though it were mana of any type to cast those spells.

Skip your draw step.
If a card would be put into your graveyard, exile it instead.
