We're Yugioh!

(We're Yugioh is all colors, even when it's not in
play.)
Up to 2 people from outside the game become
your teammates and they bring their own cards.
(If they lose, you lose as well. Your opponents turn is
in between each teammates turn. Your opponent can't
lose to infect and gain 20 life per teammate. We're
Yugioh! can only be cast once per match.)
