So this is a deck that I've been using as I wanted to play Gambit as he's my favourite X-Men and I've managed to win quite a few cubes because of it!
Obviously the optimum board is to have Invisible woman - Wong - Gambit and then Odin in one lane. To destroy 6 of the opponents cards.
Dracula in another with Apocalypse in hand. If you're really lucky, you can have it so Apocalypse is the only card getting discarded to pop your opponents cards to buff your Dracula to huge numbers.
Zabu is there as he is just broken and can get Wong and Dracula down early.
Im not 100% certain on Magik, I've just put her in there incase I need an extra turn. But might consider cutting her for Swarm for boosting up Morbius.
Mystique could be very good to copy the Wong which would reduce the need for Odin but I don't have her :(
Let me know if you have any success with the list or have some thoughts on what could make it better!
