Double Strike, Deathtouch
{x}{b}{r}, {t}: Meme X target permanents. (To
meme a permanent, put a meme counter on it. For as
long as it has a meme counter, that permanent does
not untap during its controller's untap step.)
At the beginning of each player's end step, if
each permanent that player controls has a meme counter on it, that player loses the game.
