This great deck, adopted from Reddit, is structured around surviving, Sentinel flooding, and controlling locations.
Playing this deck well means having to learn one of Snap‘s most important lessons: how to recognize what kind of deck your opponent is playing as early as possible. Are lots of 1-cost cards coming out early? It’s probably a Kazar, which means you want to play Killmonger late to flip the script. Has Sunspot comes out? Be careful, because you might be facing Infinaut (whose placement condition offers a perfect combo). Prep Killmonger for Turn 5 and Shang-Chi on Turn 6, but make sure the latter is going to be revealed after your opponent or is at least taking a big location, like Hulks at the Gamma Lab.
Bucky is a healthy Carnage snack, but you can consider replacing the symbiote with Venom later on. Carnage will also happily eat those rocks cluttering your hand (if you can spare the energy). Chavez is here for the same reason as last time (dependability and possible counters).
But the biggest lesson you need to take from playing this deck is also the most valuable. No deck can win every game, and, if you’re playing a control deck well, you’ll learn that lesson when things are at their ugliest. For those times, remember that escape over defeat saves you cubes and minimizes your fall down the seasonal ladder.
