Praos, The Peacemaker

Reach
Hydras you control have Defender.
If damage would be dealt to a Hydra you own,
put that many +1/+1 counters on it instead.
At the beginning of each end step, you may have target opponent gain control of another Hydra creature you own. If a Hydra creature you own,
but don't control died or attacked you this turn,
you may transform Praos, The Peacemaker.
