Marvel Champions - Old Hero, New Tricks: X-23 Sidekicks Honeybadger 

Really cool game. Haven't tried Sidekick yet, but my first thought was Vivian.

I use two Clarity of Purpose in my version one for Honey Badger and one for X-23 for double the pleasure. Mutant Education x2/x3 to get Regenerative Longevity back into the deck and X-Mansion to heal Honey Badger. By the way Suit Up is pretty great for her because if you got one in your starting hand you can play both Honey Badger and Sideckick immediately, then use Suit Up to tutor upgrades (Inspired, Danger-Room Training, and Clarity of Purpose) later by using the ally to pay for them. i also got pretty good results with Scarlet Witch and her sidekick brother Quicksilver (Can ready him once per phase), Mighty Avengers, Inspired and Skycicle are pretty scary in this configuration. Vision and his sidekick Vivian (+ 2 THW or ATK) works pretty well and it also makes Reboot even better. Nova and his sidekick Ms. Marvel are also pretty dumb with Side by Side.

The deck you linked does not seem to be the same one you played on the video. No gametime, danger room training, etc

Would suit up let you pull 1 card from deck and 1 from discard or do they both have to come from same place?
