Card Info
After the initial setup, any time either you or your partner gains an Ally (from any game effect other than this card), the other draws an Ally at random from the Ally deck. If he currently has no Allies, he keeps it. If he does have one or more Allies, he keeps it and then chooses one of his Allies to reshuffle back into the Ally deck.
