Writhing Phytohydra

Convoke
Writhing Phytohydra enters the battlefield with X +1/+1 counters on it.
If damage would be dealt to Writhing Phytohydra, instead prevent that damage, remove that many +1/+1 counters from it, and create that many 1/1 green Saproling creature tokens.
It sows seeds of fear wherever it grows.
