Both me and a friend got it in the first week and were confused about how easy it was this time. We thought there must have been some change to get us through more easily.

I used a Daken Destroy Deck (deadpool and taskmaster did most of the work), He used a galactus/nimrod deck.

Edit: I will say, the Daken deck has been underperforming since hitting infinite, Not sure if that's because of a different meta in conquest or it it's just that i've been getting unlucky with it, having lots of fun with my thanos/death deck currently in conquest.

I just started hitting infinite 3 seasons ago and have just hit it again this season. It's hardest to hit the first time! I find the best way to crack those last few ranks is to be running a deck different from the current meta so it catches people off-guard. This deck got me to infinite this season and I have a 68% win-rate with it https://snap.fan/decks/260890/

I got most of my cubes this month when Shuri's Lab was featured, but it ended before I got infinite. I finished by using a control/disruption deck. Spidey, Polaris, Magneto, Jugg, and Storm to mess with them, Angela, Kraven, Jeff, Kitty, Cpt Marvel, Vision, and Silk to get power on the board, Shang, Enchantress, Cosmo, and Armor as tech. Mix to your hearts content.

Not yet this season, but I have the past few seasons. My decks are always changing, but unless Rogue and Enchantress are popular I find Dark Hawk to still be very strong, I like to run him with SHIELD and Devil Dino.

I got to 95 then slid all the way down to 80 as I was tinkering and didn't adapt to the meta quickly enough.

Climbing my way back to 88 so far with SeraSurf and DarkRocks. Trying to be disruptive but they're not disruptive enough to win..

Evo decks are hurting me every time to consider putting in Cage.
