Runs so well, can win almost every game, at least in my experience thus far. Definitely one of my favourite decks.
Slotted in X-23 in place of Wolverine, now it works even better with a ton of surplus energy and her synergy with Killmonger is just the icing on the cake.
Slotted in Black Swan in place of Bucky/Winter Soldier, performance seems fairly similar either way.
Have experimented with Cull Obsidian in place of Destroyer, but the Destroyer can sometimes be essential to the end game, so again; on the fence with that one.
If you're missing a card or two it can still perform well, there are many good options for subs. Electro, Angel, Nico Minoru, Yondu, Knull, etc. This deck even runs pretty well without The Mad Titan himself, so don't ever feel like you can't slaughter some fodder with the best of us! ;P
