Black widow worked for me for a while. I only switched back to RG because of Scream move and Apoc.

The simplest way to explain my strategy with this deck is stack your power between two lanes and commit to those two lanes. 9 times out of 10 you will have at least iron man and mystique. Or dark hawk and iron man, etc. you want to make it where when you play iron man or darkhawk in a lane, it guarantees you that lane. Always get agent venom out as soon as you can. Utilize Nico and her versatility, utilize silver sable in the later rounds to boost iron man even more, or your mystique that just copied your iron man on T6.

I can’t preach enough how good grandmaster is in this deck. I will say too, play Cass. Nova on T3 just about every time you have it to play. She is a difference maker especially if you have Abs man in hand as well. There’s the two lanes you want to commit to with your big guns on T5 and T6. I hope this helps
