Mothra

Flying
Each player can only control 1 "Kaiju"
creature at a time.
If Mothra would die, instead exile it
with three egg counters on it.
At the beginning of your upkeep,
if Mothra is exiled with an egg counter on it,
remove an egg counter from it.
Then if Mothra has no egg counters on it,
return it to the battlefield.
