Phoenix of Ggantihre

Flying, haste
At the beginning of your upkeep, if phoenix of Ggantihre is in your graveyard or exile, put a magma counter on it. You may cast phoenix of Ggantihre from your graveyard or exile as long as it has 5 or more magma counters on it. Then remove all magma counters from Phoenix of Ggantihre.
