マナ喰(ぐ)らいのフェニックス

Flying

Managorger Phoenix can't block.

Whenever you cast a spell, if Managorger Phoenix is in your graveyard, put a flame counter on Managorger Phoenix for each in that spell's mana cost. If Managorger Phoenix has five or more flame counters on it, return it to the battlefield and it perpetually gets +1/+1.
