Abio-Regenesis

Red and green creatures you control have riot.
At the beginning of each opponents upkeep, that player sacrifices a permanent. Create a 0/1 green
Hydra token with X +1/+1 counters on it, where
X is the sacrificed cards converted mana cost, this
token has trample and 'when this creature deals damage, put that many +1/+1 counters on it'.
If Abio-Regenesis would be destroyed, exile it
instead. Exile all permanents you don't control.
