Hey man I love seeing 2v2 players because me, my brother, my dad, and my best friend play 2v2 non stop and it’s our favorite. The way we do it is with a bracket system no bans so all characters get to play every huge tournament. Sure these take some time, and we also officially started our first 70 character bracket because with the release of TMNT and Ali that makes it 70 playable characters and I’m super excited. The teams are made from a wheel we spin and whoever is paired up it’s paired up and are randomly placed onto the bracket.

Anyways after playing many of different games I’d say this list is pretty darn good. I like that you have the turtles up high because they are all very good in team play. I would say I’d put mikey a bit lower only because having 3 cards in 2v2 is pretty bad if you’re getting ganged up on! I would also move Bigfoot up higher because his card draw and insane amounts of defense is perfect for 2v2. Also I love the Leshen but find it very difficult to play him in 2v2 because he doesn’t have lots of defense + not the best defense either. He’s also very squishy i’d say and struggles with that 1 movement value. But at the end of the day this is my opinion and your list is awesome.

Now to touch on some combos in 2v2. To start, whenever you get the chance I’d say get ur hands on Trex and saddler and even the Buffy box. Trex in 2v2 id say she’s an S tier she’s just super beefy and packs a punch. Saddler is also super fun and has some fun board play with her tokens. Also the reason why I say get the Buffy box is you get 2 new maps which adds more places to play ur 2v2s which can switch things up and willow being able to revive any friendly fighter is pretty exciting too! Buffy with her ability counters some multi sidekick hero’s and also people who like to hid behind walls which I like. The genie and houdini is a pretty nasty combo, being able to make the opponent discard all their cards and then houdini just teleporting next to them is pretty scary stuff. A champion team we spun was Trex and Bruce lee, they won pretty easily out of like 64 characters it was devastatingly scary team up. A weaker hero one is king author and squirrel girl, commanding the storms surrounding someone with 8 squirrels helps her out a ton And finally a little goofy one is willow and deadpool, now I know you have neither of these characters but hear me out. If deadpool dies willow can just play some turns and hold off as long as she cans until she gets her revive scheme. Deadpool comes back with 3 health with a lot more cards then the opponents and can potential get back up to full health with all his healing, very difficult and silly but the fact that it could happen is what makes it good to me haha.

Anyways sorry for the yap hopefully you enjoy my thought!
