For more 13 fun, check of the Magic: the Gathering card Triskaidekaphobia. (Specifically, counts in the art and the rules text.)

Isn't MTG a 1v1 game generally? "Each player"?

I think it depends on the format, so cards have to handle the case of many players.

I think there are quite a number of many player formats actually.

Like, in one, some number of packs a cracked, and they are passed around in a circle, each person picking one card, until everyone has a deck, and then they play.

Iirc. (Haven't played it myself.)

Elder Dragon Highlander or Commander is a multiplayer format. http://mtgcommander.net/rules.php

It is "each player" since the card can backfire and cause you to lose the game, if your opponent is clever.
