Quantum's Take

The Red Death has ways of dealing with Joker (debuff removal) and Physical Damage dealers (Dodge). He also deals Spiritual Damage, so you'll need a team that can withstand it. This is a tailor-made fight for Nightwing comps, despite Red Death's increased dodge, since he takes increased Physical Damage. I'd probably run Beast Boy on the team for survivability. The old mechanics have been removed, so there's not much to do here other than throw your best team in and hit start.
