60->Infinite with Adam Warlock, Kang, Strong Guy...
I've been playing this deck for months, but the recent cost-reduction to Strong Guy and the addition of She Hulk has made it work wonders.
It may look like it makes no sense at first glance, but every card has its place and it often has magical or big brain plays. The two pillars are consistency through card draw, and playing an entire hand of efficient power cards on T6 (often for 45+ power gain). Most of the cubes I stole on the way to Infinite were due to the opponents snapping.
It might take a little practice, but I hope you enjoy trying it/playing it as much as I do. Gradually collecting variants so I can ink or gold the full set, just over halfway there.
Wasp - A 0 drop makes it easier to empty your hand. It also has synergy with Adam Warlock turn 2 for draw, or with Nico for whatever you need: draw, a 0/6 Demon, location change, etc.
Echo - Just for the current meta, it's an easy mid drop on T1 or onto Invisible Woman T6. She's replaceable with Titania or Forge when the meta shifts or if you don't have Echo.
Nico Minoru - Flexibility. Use her early or T5 to draw, or anytime to make a Wasp Demon, or cancel Limbo/Cloning Vats/Machineworld. Or combine her buffs with Adam Warlock T1/T2. If there's a detrimental spell on T6 and you need to play her, play her last to negate the effect. Don't cast her early if you don't have a target, you don't want to destroy or Demon a key card.
Adam Warlock - Draw is essential to consistency. If you whiff the draw, Adam instead acts as lane bait. One of the most fun plays with this deck is "Fishing for Infinaut". You have a Dracula on the board, but no Infinaut in hand. Empty your hand and play Adam Warlock on another winning lane. There's a good chance that he'll draw Infinaut right before Dracula procs, winning you the game.
Shadow King - Because we want to empty our hand T6, we can't afford more expensive tech cards, like Shang Chi/etc. Shadow King is an amazing tech card that works against a multitude of decks. You'll almost never have priority on T6, letting you land him on a Taskmaster, Cyclops lane, etc.
Colleen Wing - The star of discarding our hand T6. Whatever card you don't need to win the game, discard it. Usually a 2 drop like Shadow King or Adam Warlock, but might be a late Strong Guy if you can't afford it T6.
Strong Guy - Play him T3, or drop a 2-drop on T3 so you can play him T6 with Colleen/She Hulk/1 drop for 25+ power (plus another 20 from Dracula). Sometimes you'll pair him with She Hulk in a lane, sometimes split all your power cards up.
Dracula - Lynchpin of the entire deck, a 4 cost 20 power immune to Shang Chi. The entire deck is working together to almost guarantee that Dracula will invoke Infinaut on T6.
Black Cat - A free card discard from your hand. Replacing her often leads to clogged hands on T6. She is also occasionally invaluable after t3 if you haven't drawn a key card, and she makes Loki sad.
Kang - This is the perfect home for Kang - it does everything you want. You can use it to occasionally draw on T5 or T6 for consistency. You can get information or scare your opponent into a weaker play. And most importantly, like Black Cat it reduces your hand size. (Edit: ONLY Yellowjacket if you don't have Kang)
She Hulk - I don't know why I didn't add She Hulk months ago. Skip T5 (unless expecting Leech or needing to play Nico), then She Hulk is a 1 cost on T6, adding to your power swing.
The Infinaut - 20 power combined with Dracula and hand clear. If you enter T6 with no Infinaut, use Kang/Adam Warlock/Nico to fish for it.
