I pulled a capiw and let me be honest, He is a battlegrounds monster even without dupe(his dupe is irrelevant for bgs anyways).Sometimes all you need is to play defensive, and capiw allows it by blocking a million hits (For instance, you wanna block and play defensive against bishop to prevent him form launching sp1). And capiw ends every fight in sp2 if it crits (easy 200k+ damage and invest on crit rate stat focus and it crits most of the time). And he goes well with hulk, s99 and best with cap relics as well. Mojo is a great bg dual threat unduped and Hulkbuster is a monster. Ronin is useful for niche situations.7* Angela and namor are the ones I don't wanna pull as they essentially want high sig to shine.
