Ydranatos, Ancient Chaos

Intimidate, menace, trample
Whenever an opponent shuffles their library,
put a +1/+1 counter on each creature you control.
Whenever another nontoken Hyrda you control
with power 6 or greater dies, create two 3/3 green
Hydra creature tokens. If its power was 6 or less
create three 1/1 green Hydra creature tokens
instead.
