Thrambos, the Immortal

Vigilance
Whenever Thrombus, the Immortal dies, return
it to the battlefield with X +1/+1 counters on it
at the beginning of the next end step, and you lose X life, where X is the number of times it
has left the graveyard this game.
"Careful, immortality is not an easy thing to achieve.
I doubt it has lived this long by being careless."
