Charlotte, Chaos Incarnate

Indestructible
As long as your devotion to white, blue, black,
and green is less than ten, Charlotte isn't a
creature.
Creatures you control have trample.
At the beginning of your end step, put a coin
counter on another target creature.
Whenever a creature with a coin counter on it
dies or is put into exile, return that card to the battlefield under your control.
"That's mine. Not nice."
