This deck MIGHT be TOO GOOD. Marvel Snap 

Love to have you here bro

That's actually a really good question, but it's difficult, I honestly think this deck is so good because it has it's own power it puts out, while making your opp less consistent with rocks and widows bite. Tech Card soup is probably just the best counter, you can't really go over the top of it easily because Thena/hawk/Angela with potentially double iron man gets huge in two lanes. Bounce is pretty good because they can play for all three/ play for two really well. Other then that you'd basically need some combo of tech cards in my mind to beat hawk/ iron man stuff. (rogue, enchantress, shang)

If you lose all your bubs in 5 games that's literally never a single decks fault, taking a step back and snapping and retreating better is very important. You can disregard my advice as copium, but its honest.
