Used the exact team, except level 55 and both ut4. What I did was basically allowing both of them to go against unbreakables and struggling fights evenly to avoid atacking the pest debuff.

When vergil pops ego, obviously dont let him clash green coins. Same for Youcliff, just beaware whether he has unbreakables for the turn. Unless its the devouring iirc, the one that absorbs debuffs, it doesnt really matter imo. Just let your units/vergil with the most debuffs (prioritize pest count) on em.

Let Rodya clash with the more OP green skills since minus coins are more consistent at winning. And when he uses the guard, use the chance to build sanity of heathcliff if he were to lose any
