That set presents some design challenges. I think QoH is best at flank, not tank, so she can draw fire from the actual tank and maybe give it a chance to heal or cast. Im also a fan of rainbow defenses, which make stacking less obviously great—but you’ve got no blues listed. Finally, I’m not a fan of using the typical color-debuff heroes (e.g. Evelyn) without a matched-speed matched-color attacker (e.g. Lianna).
So perhaps something like Evelyn / Inari / {Kunchen | Kageburado} / QoH / Lianna
Personally I’d put Kunchen center in this configuration, but if prefer fast attack style defense, Kageburado is the master of that style—just get that mana troop up to 11. Victor and Zim seem to play better on offense than defense.
