Well, no other Eddie survives that "Vault" on auto. I've tried them all. But IME's fury is a massive hit and, due to relics, fires enough that it tends to just wipe out the other side in 1 hit. Note, I've got him full power, fully shared, and with Warlord talismans.. so there are boosts there. But even just swapping IME with FFE, also full power.. I can't auto-play that vault.

Truth is Crusader Ed does the best after IME for me Crusader can auto some, but will lose at times. IME has yet to lose a round, although it's only been like 2 or 3 runs since I got him.
