Anybody have any tips for doing this?

Good character combos, etc.? Load up on health talismans?

I feel like the best characters I have are the Allied Soldier (deals a ton of damage to everyone) and the Wickerdog of Night, because he can heal. I've experimented with other characters and powered them up, but they seem useless in comparison).

Also, does the Wicker Eddie make the original No Prayer Eddie not worth using? He seems much stronger. And I'm not sure if there's a benefit in swapping the leader position. Thanks!
