Greed, Keeper of The Hoard

Flying, Haste, Indestructible, Trample

You may exile Greed with three slumber counters
rather than pay this spell's mana cost.

At the beginning of each opponent's upkeep, they
may create a treasure token. If they do, remove a
slumber counter from Greed. When the last
slumber counter is removed from Greed, put it on
the battlefield from exile.
