Played this from rank 50 to rank 100 in a week.
This deck focuses on playing high value/energy cards, especially once they get buffed by sera. All these cards essentially generate at least 2 power per energy by themselves, with some of them going higher than that. The secondary condition is to gas out to activate strong guy, and bait cubes on t6 by pretending to not play a lot of cards and then dumping 4-6 buffed cards out of nowhere.
Some cards that would be upgrades
Sif -> Hell Cow
Captain America -> Mojo (maybe)
Some cards that can replace Maximus if you don't have it
Punisher / Ironheart
How to play this deck:
Turn 1: always skip, unless there's +1 energy location and you have okoye.
Turn 2: Okoye if you have it, otherwise skip, sometimes you'll want to strong guy/angela here based on how heavy your hand is and if you have sera.
Turn 3: This is where it REALLY depends on your draws. If you have Nakia it's definitely a Nakia play. Otherwise if you don't have sera and a heavy hand, feel free to drop Angela/Strong guy/America/Wolverine here
Turn 4: Nothing special, count your cards, make sure you can gas out on turn 6 if you don't have sera. Play cards if you need to. Shangchi is usually fine for naked here if you have to
Turn 5: Sera, or same as above, play as much as you need to gas not. Save your discards and Maximus
Turn 6: Empty your hand, try to predict where the enemy will likely go, you have a lot of power usually here, with an average hand you should be able to easily drop 20+ power, and a good buffed hand up to 40 power in a turn.
Interesting combos:
Maximus -> Shangchi to guarantee a kill on dinos.
Maximus to deny enemy's Strong Guy and Dracula -> Infinaut combos
Nakia w/ Wolverine in hand and discards -> buffs wolverine before you drop it
Mister Sinister / Wolverine -> Knowhere
Mister Sinister to fill your locations + Wolverine discarded -> Sanctum/Kyln and other locations to steal
