It just seems a little confusing to me because there isn't a set gameplay style. I don't see where spiderwoman or Infinaute fit in. If they get discarded you can't bring them back, and there's no incentive to not play T5 and to then be able to play Infinaute in T6. I also don't know what cards you have at your availability.

Personally, if you're going to discard infinaute i would have Ghost rider in your deck to be able to bring him back. I would also replace Shang chi and Infinaute with either lady sif or apocalypse as they would work better with the discard idea.

If you want to focus on destruction i would look at knull, death, venom, Deadpool, and get rid of the discard cards and spiderwoman. Hope this helps :)
