If damage would be dealt to this creature, put that many +1/+1 counters on it instead.
"Look at this creature, so like the Conclave it serves. Cut one head and it grows two. Damage it and it flourishes."

Phytohydra's ability doesn't prevent damage. Damage that can't be prevented will still be replaced by +1/+1 counters being put on Phytohydra.

If Phytohydra blocks or is blocked by a creature with first strike or double strike, Phytohydra will get the counters during the first-strike combat damage step before it deals its own combat damage during the second combat damage step.

If another effect would prevent damage from being dealt to Phytohydra or replace it with something else, Phytohydra's controller chooses which effect to apply first.
