Team 2 easily. Talisman casts a spell on Zatanna so that she cannot speak backwards (I'm sure she can do it somehow), while Thor distracts BA. Once Zatanna is neutralized, Talisman strips BA of his powers. She then shrinks both of them down and tosses them in the pouch for safe keeping.
OR, Talisman commands the air spirits to keep Zatanna from breathing (and therefore speaking) until she passes out. Thor distracts BA long enough for Talisman to neutralize him by absorbing/negating the magic which powers him (as I believe she did with one of the wrecking crew in OF #4 or #5). Once they are both neutralized, Talisman then shrinks them and drops them in the medicine pouch.
Either way, if Talisman is written properly Team 1 should go down pretty quickly.
Even if, however, Talisman is written poorly this most likely stalemates, with Team 1 still having a slight advantage IMO.
