I realized that I don't keep up with modern stuff enough to have a reasonable guess here. A cursory Google check reveals a metric s**t ton of new teams, books and configurations over the past decade.
I will plug what I *want* for the next box, though: Chuck loves Spidey, I love Spidey. Sinister Syndicate: 80s Beetle, 80s Boomerang, Armored Rhino, Comic Speed Demon, Classic Shocker, Spider-Man. I swapped Hydro for Shocker since Hydro's been done twice, and we haven't had a classic (original costume) Shocker yet.
