Ezhu, Supreme Hydra

Hydras you control have Trample
Ezhu enters the battlefield with X +1/+1
counters on it.
At the beginning of your upkeep put X +1/+1 counters on hydras you control where X is half
Ezhu's power rounded down.
If a hydra you control were to die, you may
sacrifice it and move any number of +1/+1
counters on it to another target hydra.
