This is one of my go-to decks when I just want to chill. I play it since like 5-6 months, almost since it was created by Lifecoach and presented by Fishou.
It's a cool deck for missions that need to play Ongoing cards/missions that want you to have 40+ total power in a game.
An ideal turn-by-turn play is : T1-2-3 : you try to fill a lane with Ant-Man/Ebony Maw/Armor/Mister Sinister/etc - T4 : Omega Red - T5 : Iron Man - T6 : Onslaught
• Basically you lose on Enchantress. • You can beat Galactus decks with Iron Man + Onslaught + something if they didn't send you a Goblin or a Void. If you don't have these cards, retreat. • You can reach hard locations with Nightcrawler, Squirrel Girl, Mister Fantastic, Omega Red.
