High Voltage

With Arishem, Agatha is guaranteed to play herself turn 2. That's a guaranteed 14 power turn 2 with less chance for her to mess up plays.

Havok is a 2/12 if played on turn 1.

You can sit on Maw until the final turn, since there's only 3.

Warlock right turn 1 is so good.

Morph is best on 2, he and Zemo can be earth-shattering for 3 energy because of what others are playing in this format.

You'll have plenty of options with Arishem in the deck, and Blob and the Hulks round everything out.

Shang can be useful, but isn't really on-theme with the rest of the deck. Wiccan might make a good sub for Arishem; Playing him on 1 when generated by Arishem was an instant win.
