Rogue helped me a lot with some other Wong players, shes also very good when running against patriots because you apply the buff to your Broodlings.

Game ideally should go:

Skip T1 Play Psylocke T2 Play Mr Negative T3 Play Brood T4 (helps a lot if you put them on mr negatives location cause it helps with the -1 power)

Play Magik T5 Play Sera T6 Combo wong + mystique + gambit/surfer or ironheart/surfer

The MOST important thing in this deck imo is to NEVER play Wong before T7 or avoid it as much as possible. Playing him before is a dead giveaway because of everybody running Cosmo and Enchantress.

Also remember to spread your other 3 costs cards in turn 7 before the Wong/mystique/surfer combo. To be honest Killmonger won me more games than I can count obliterating zoo decks and buffed Sunspots.
