Corvus, Domino, Blade and Starky for sure. You can also put GR in there for synergy. Or Killmonger and Sabertooth synergy. For which path, I think the one with Angela->Gwenpool -> Venom path should be the easiest.
Use spidergwen to get the last charge on corvus. Hit until she dodges, then parry her then heavy. With 4 charges, corvus is a great choice for the collector to just "revive" until he's down. Quake as well can be a great choice. Do you have Nick fury? He gives everyone three dodges, which again with corvus, can be a great option for getting huge chunks of the collectors life off each go.
