I found this deck here on snap.fan, the person who is credited there is Domoknows - If you're here, THANK YOU MY DUDE.
So I took the cheap ass route, and I went back to what I kept facing and losing to. That said, in my entire run throughout the late 80s and through the entirety of the 90s I face, I shit you not, ONE BOT. And that was last night. Before that, NONE. It was everyone who either emoted, had spotlight avatars and played the game for real. I don't know if it was because I waited a few days before I could do a full push, but either way it was a rough going. That said, it also makes me feel the most acomplished hitting infinite. I didn't cheese my way through screwing over bots for 8 cubes. I had to find the deck that would work, and not only that I would have to stay in when I had to trust that it would work.
That said, I will say without even the slightest hesitation that this deck not only runs well, but FEELS great to play. YES there is RNG involved, but for the majority of it any pulls from your deck are far from bad. And if you've got Lockjaw? Damn.
I am at CL 13.5k, I finished infinite with about 7.25k snap points and ended up right at rank 9,001 and I started playing at Global Launch.
Ideal Playlines (HT to Snap Judgements on YouTube/Twitter for style)
T1 - Stone. Literally a stone. That's it. You have nothing else. Just be careful what you use here
Mind stone. If you have mind stone, and lockjaw... you're cookin' with fire. You're making a stew. Preferably mind stone, don't even think about Time Stone. You use time stone and I will come to your house and slap you. It's too important to use as ramp, there is ONE exception - You've got lockjaw in hand and you have a bunch of low cost cards/jeff. Then MAYBE, but preferably not. I would also strongly recommend not considering using reality stone. There's a lot of tough locations that can brick you, so having that in hand has saved my bacon countless times.
If you can't stone, pass.
T2 - Jeff >/= SINGLE stone (esp if you have 2 in hand).
You want to be able to Caiera on 3 and LJ/Stone on 4. If you can't do either, it's another pass.
T3 - Caiera > LJ > Time Stone + Jeff > Wave
Wave ONLY if you have a solid hand and can really rush prio on board, especially if you have Alioth or Skaar in hand. T3 is where you can see if you have a good chance at winning. I can tell you that even if your hand is bricked with a bunch of big cards, it does NOT mean that you're going to end up with a tiny blob. I didn't play my last push to 100 on a computer, but a tracker can be a HUGE help, but trust me - when you play it a ton, I can assure you that that you'll start to just know if your blob is going to be enough. You can also CONSIDER a move toward Galactus. Do you have a full hand and Dino along with Alioth? You got this. You also need to remember that you need to win more than 1 lane. Do you have Dino in hand? Welp, maybe it's time to ramp into Dino to get Skaar cheaper.
T4 - Caiera + LJ Time Stone (pref time stone if dino) > Wave > Jeff
Here's where things get spicy. Are you winning in prio? Do you have Galactus and Alioth in hand? Can you nail priority? If so, you're now a Galactus gamer. You don't want to play him TOO soon, and you want to make sure you keep priority. But you can start planning for this win. Do you have a power stone and jeff AND have Lockjaw and Prio? Then you got this. Wave and stone and prep for Galactus T5. I cannot tell you how often this won. People stayed in. Like I do not know why, I really don't. I did not throw Galactus down on 5 without Alioth in hand, and I for SURE did not on 4 without Dino and a decent sized hand along with either Alioth or a big card on 6 to prevent an alioth played against you.
T5 - Cycle Stone in LJ and anything from previous turns >/= Skaar > Dino > Marvel
You're basically now setting up a win. You have to remember that if you have blob, you almost certainly have that lane locked. Do not forget that you can throw him in your paltry LJ lane. He will not get pulled in and that lane is secure.
If you have Dino on board from a previous game, you might be able to throw down Skaar and cycle a stone or two, even more if you had to play time stone last turn. This could be good. This could be your wincon
T6 - You all know what this turn is. It's blob. Or it's Magneto. Or it's Thanos. If you can't solidify those lanes you've already won, and you think there's a chance they can't come over top of you.
Things you NEED to watch out for
Shadow King - Listen, if you ramp Blob out early, I never ever ever had an incident where I didn't fear for his safety. I rarely saw shadow king, but the few times... well, I didn't end up winning that lane easily, if at all. Actually I think it only happened once. He can end you. But that's ONE LANE.
Enchantress - Okay, so I don't think there's a ton of people who are going to blow through 2 turns to enchantress and end you, but with Sera I have seen it happen. If you see them with Zabu and then Sera.... be very afraid. They can do very much, one is Enchantress.
Shang - Obviously. Caiera isn't going to be your protection in a large percentage of your games, so Shang is a huge issue. I will say one of my favorite wins was them trying to Shang my magneto and I cycled a stone through that LJ lane and it pulled Caiera. Yes, I cackled.
Scary Match-Ups
Black Knight - I've realized I'm not great at this deck, but it can put out a SCARY amount of power. I've even seen some people running a Blob version. There are a few variations, both of them are scary. Being able to throw down a 20 power blade and then ghost rider another 20 power card back onto the board is a LOT of power, and more than you can probably put out. Especially since they run Skaar. Hela can be unpredictable, but it's hard to know what's going to happen.
Sera - As mentioned above, this can be dangerous. The Sera/Zabu lists are going around and they can decimate you, they can pull a good card out too early. I've had my LJ and Caiera ended by a Gladiator. That don't feel great. They are also carting around a Legion and, again, that can be... a problem.
Substiutions
Caiera: This is a hard one. The most common loss was shang. I barely saw any shadow king, and the one time I did I still won the lane. But not being able to block a destroy deck, or protect your stones (which, to be fair, can be tough due to board space) is a struggle. But to ensure that you have a confident play for your 6 drops, being able to play on Death's Domain or even Altar without having to resort to space stone, is great. Also Armor. She's cheap. She's effective. Sure she's only one lane, but it can be enough.
If you're giving that up, I really think Nico would be a good option. You want to get the cards you need and you want to get the ramp you desperately need. You lose a lot on power and protection, but at least you've got some draw to get the cards you need. Iron Lad also isn't the worst option, nor is TaskMaster.
You could also, ick, use Leech.
Skaar: You know.... Doc Oc might not be the worst thing to happen to this deck. Yes it adds some crazy RNG, but you can kill their entire hand and run away with the rest of your game. Oh no, they Shang'd you? Well, they don't have Shang anymore and that lane is LOCKED. Possibly Red Skull, although the downside is a problem. Orka is another solution. It's hard, because you're spreading across lanes but hey, it's power for your Blob. Hulk is ALSO a potential replacement but again, the same conditions apply although you get an extra power for a lack of restriction. Death no, Infinaut ... maybe. She-Hulk is also a maybe.
Blob: ... no
Galactus: I'll tell you, this is a tough one. I don't love Galactus but it really gives you a whole other wincon, but it can also be disappointing to pull him out of LJ. I speak from experience. But if you are going to swap him, add in another big boy. See the section on Skaar replacements.
Locations
Excellent: Elysium, welcome back to zero cost stones! Kamar-Taj, hello all your stones or as much energy as you could ask for, Sinister London (play carefully!), Superflow, Wakanda - OH, you don't have Caiera? Caiera at home, Nexus (BUT BE CAREFUL), Quantum Tunnel - Oh a free Lockjaw you say? Yes please. And enjoy the insanity if you pull LJ out and cycle stuff in. I don't even know.
Good: Cloning, Baxter, Aunt May's, Altar of Death/Death's Domain (with Caiera), Abbey, Vibranium can be... excellent. If you have your hand full of what you need, this can power up blob like CRAZY, White Hot Room, Quantum Realm (Free stone buff, and a tiny hit to Dino/Blob), Gamma Lab, Throne Room/Warrior Falls, The Peak (situational! Dino/Blob in hand? Laughing. All your bigguns? Sadge)
Okay: Hotel Inferno (yeah, it's thinning their deck but it's killing their potential counters), Rickety Bridge (with Caiera or Armor), Olympia (also situational), Sacred Timeline, TVA (reality stone, wave and Galatus), Morag
Shit: Miniaturized Lab, Lechuguilla, Mindscape, Space Throne, Luke's Bar, Triskelion, Weirdworld (obviously), Tarnax IV (don't forget, ebony maw exists, as does Shanna), Ego/Worldship...
