Realize the in the Gauntlet you are not battling against other players. The enemy teams are entirely configured by the app.

Sometimes, if your'e just one battle short of something, and you HAVE to use a weaker Eddie.. swapping talismans around can help. For example. Destiny talismans on Mummy Eddie may make him survive a bit longer. I wouldn't normally waste a set of Destinys on Mummy Ed.. but for a single gauntlet battle, it can be worth a quick swap.
