Target: Symbiote vs Symbiote Objective
Duels Search..
Symbio (symbiob) = Symbiote Supreme (custom pic, but same as actual champ)
Symbiote (Symbiote 2098) = Carnage (custom pic, but same as actual champ)
Carnage (Carnageanti) = mid 6* Carnage
Duck (Duck 22) = 3* Carnage (thinking maybe a VtD, found Carnage anyways)
Also, Knull counts too (in Side Quest), but if pairing with the Mystic/Mutant side quest objective then Sym.Supreme is the only champ that can be on your team.
