1. Loki - Deadpool's HF will allow him to eventually slip the scepter out of his hands. Loki was intentionally jobbing here too which makes this easier
2. Captain America - Wolverine beats him straight up
3. Ancient One - Nightcrawler to surprise her, anyone else would just get taken into the Mirror Dimension.
4. Red Skull - Beast
5. GOTG - Colossus and Storm. Most of the team fights CQC so Colossus draws fire and Storm fries them.
6. Thor - Kitty Pryde. Everyone else gets oneshotted, but Pryde might be able to phase kill him.
