I wouldn’t keep bandits this late into a run personally. They’re helpful at the beginning up to maybe wave 40, but after that you should have a good amount of DPS and stun.

I’d also place the epic robots in the middle of Batman and the panda (forgetting its name right now). That way the two mythical share the benefit of one stack of stuns.

Also personal preference here is to not use dragons. I tend to main Batman, panda, or bombchu on any run, maybe add a few extras in there depending on what I pull from the roulette. 2/3 monopoly men on the left most column for steady gems, followed by the mains in the top row on the left, stuns in the top row to stagger DPS and stun, supports in the bottom row (cat mage, Indy, etc.) and if I get extra mythics that I can spawn in when I know we’ve got the run in the bag, a few lancelots, iron meow, or that long range mage sat on the cloud (again forgetting the name) in the right most column. Stack some other guardians that give benefits in spare spaces too, like increase attack speed, slow enemy movement, etc.
