I've been having some pretty consistent wins with this deck, so I thought I'd share with y'all!
The main crux of this deck is Jubilee, of course, letting you pull some powerful 6 cost cards earlier than normal and flooding the field with a good amount of power. Adding in Lockjaw, you have even more opportunities to up your power while swapping out some good "on-reveal" effects for raw stats. America Chavez is great as well, essentially making this an 11 card deck as opposed to 12, based on how she works.
Main combos: T2 Domino; Lockjaw-->Jubilee; Lockjaw-->Storm; Jubilee-->Odin; Jubilee-->Infinaut
Lockjaw-->Jubilee basically gives you two Jubilees, while also putting Jubilee right back in your deck. T2 Domino gives you a guaranteed T2 play, and having no C1 cards negates any Killmonger use by your opponent. Lockjaw-->Storm let's you close off a lane while potentially swapping Storm out for something powerful. Warpath is great because I usually have an empty lane when playing this deck anyway, so he's consistently a 4/9.
The only card I'm iffy about is Iron Lad. He has the potential to copy Jubilee, and subsequently take away your Jubilee play (since he'll then pull her after copying her card text). Might swap out for Enchantress for some "ongoing" negation, or White Queen to keep the 4/6, and get a free card out of it.
