First of all I don't own Mystique, Wasp, Debrii or Brood so I don't know if this cards can be 100% recommended.
I don't recommend Abomination cause there are better turn 5 plays.
-Iceman instead of Ant Man if you prefer more disruption over raw power you can pick one of those 1 drops.
-Onslaught instead of the Thing, I think onslaught is overkill (Haven't tried him)
-Cosmo over Cyclops if you fear Counter cards and want some Disruption.
-I'm not a 100% sold on Squirrel Girl, but she is good if you don't draw Ultron (Could run other 1 drop)
How to play:
Your lanes should look like:
-Angela + Patriot + Strong Units.
-Blue Marvel and Ka-zar on the other lanes.
-No ability units + Ultron
-Don't Squirrel Girl on turn 1
-If you don't run Cosmo or you didn't draw him play around Enchantress or Rogue (avoid stacking ongoing units)
-Play your biggest units on the - Power lanes (Cyclops, The Thing, Ultron)
