Sunflower

Create a 1/1 Plant Sunflower with 10 Phase counters
on it. "phase counters are removed at the beginning of
each phase change"

Fast Recharge (If you cast this spell from your hand,
exile it with 7 phase counters on it as it resolves, if it
doesn't resolve still exile it with 7 phase counters on it,
once all phase counters are removed, you may cast this
card from exile by paying its mana cost.)
