Crypt's Thornvine

Persist (When this creature is put into a graveyard from play, if it had no -1/-1 counters on it, return it
to play under its owner's control with a -1/-1 counter on it.)
Delirium - As long as there are four or more card types among cards in your graveyard, Crypt's Thornvine has "{g}{b}: Monstrosity 3." (If this creature isn't monstrous, put three +1/+1 counters
on it and it becomes monstrous.)
