Who should be my next 6* r3?

KingInBlack

I'll toss in a wildcard and say Sigil Witch since Cap and Guardian need the dupe and preferably high sig before the r3 investment imo. Sigil witch is dominant for me at r3 and doesn't need the sig to do any of it.

She hulk

I say shehulk just cuz she is almost always a solid counter for this big boss fights kabam puts out
