John Cena

Flash, Haste, Indestructible.
When John Cena deals combat damage to an
opponent, give them a Doom counter. A
player with 5 Doom counters loses the game.
If John Cena dies or is exiled, instead of going
to the Command Zone, reshuffle John Cena
into your library. If you draw John Cena, reveal
it and put it into play.
