Loki

When no player is Earth, reveal Loki. When you
do, all Villains win the game.
You may flip this card face up at any time. When
you do, choose one of the following;
• Two target players switch hands until the
beginning of your next turn. Those players may
use mana as though it were mana of any color
until then.
• Two target players switch all their nonland permanents.
