The Morgue

At the beginning of each player's upkeep roll a six sided die. If it is a 6 put a 0/0 Morgue Zombie token on the battlefield that has X +1/+1 counters with "At each of your end steps, remove a +1/+1 counter from this creature".
"I didn't get here! Don't you get it! This isn't me! I'm not me!"
