Arives- Destroy target creature.
First Strike,
{b}{g}: Exile Margit from your graveyard, with
three time counters on him. Whenever a
permanent you control is destroyed remove a time counter from Margit. You can cast Margit from
exile without paying his manna cost if there are no
time counters on him.
