X-23 - The Crazy Nastya$$ Honey Badger

While I am certain I am not the first to go for this angle, here is my take on making a badass Honey Badger who sticks around and helps Laura do her thing.

One of the nice things about Honey Badgeris that she is an X-Man. That means she can benefit from Danger Room Training and X-Mansion. You can still put X-Force Recruit recruit on her. That, along with Team Training, Uncanny X-Force, Inspired,Reinforced Suit and Sidearm creates a ATK 3, THW 3, 7 HP beast.

You likely won't get all this out at the same time during a game, but she gets continuously better as you do.

Meanwhile, Deadpool and Deathlok can benefit from Sidearm and the extra Inspired. All of them can make use of Ready for Action and Regroup to stick around.

Meanwile, X-23 has X-Gene to use her own cards, and Mutant Education to keep shuffling them (and Honey Badger if necessary) back into her deck.
