Medula de Metamorfo

Encantamento, 2UU (4)
No início da manutenção de cada oponente, aquele jogador revela o card do topo de seu próprio grimório. Se for um card de criatura, o jogador coloca o card em seu cemitério e Medula de Metamorfo torna-se uma cópia daquele card. (Se o fizer, ele perderá esta habilidade.)

Enchantment
At the beginning of each opponent's upkeep, that player reveals the top card of his or her library. If it's a creature card, the player puts the card into his or her graveyard and Shapeshifter's Marrow becomes a copy of that card. (If it does, it loses this ability.)¹

• 5/1/2007: If the revealed card is a creature card, Shapeshifter's Marrow becomes a copy of that card permanently. It's no longer an enchantment.
• 5/1/2007: In a Two-Headed Giant game, this ability triggers separately for each player at the start of the opposing team's turn. If the first ability to resolve reveals a creature card, Shapeshifter's Marrow becomes a creature. If the second ability to resolve also reveals a creature card, the ex-Shapeshifter's Marrow then becomes a copy of that creature.
