Monkey King’s Ascendance

At the beginning of your upkeep, create a 4/4 red and green Monkey creature token with haste.

Whenever a Monkey you control attacks, it gains +X/+X until end of turn, where X is the number of Monkeys you control.

If a Monkey you control would die, exile it instead. At the beginning of your next end step, return it to the battlefield with a +1/+1 counter.
