Themes with variety would be nice even if it's just a small linking like a random teamup or handled like the Kevin Bacon game or even just other similiarities to their individual teams.

Like X-Force v3 Wolfsbane relates to Secret Avengers Valkyrie (Asgard and spec ops), connects to Sin (fear itself hammers, plus excuse for pre-skull variant) connects to FI Hammer Wielding Juggernaut, which connects to modern Juggernaut Colossus.

Pretty much you can connect entire figure waves like this thanks to Marvel story telling. Like Modern Venom, X-23(unmasked), and female ghost rider, which also connects to Big time spider-man/scarlet spider which also connects to classic clone saga era Kaine thanks to the venom symbiote connection. You can go on and on connecting the waves this way if you really tried. Could probably do it to the current ones too.

They can also do other themes that cover a wide variety, like say an all asgard theme that covers New mutants Dani(has a side job for hela), asgard's Hela(with pip the troll) or female loki, valkyrie, modern Thunderstrike, classic thunderstrike, FI hammer wielders, Thor Buster ironman, new Mutants Warlock(helped save hela) or Cypher(Helped save hela), a Douglock variant, X-Force v3 Wolfsbane(has an asgardian bf/baby daddy), X-Force v3 Elixir(brought out of his coma by hela), Multiple man no mask in trenchcoat with eye M(did a case for Hela on finding pip the troll), etc.

This covers an area of marvel, and also covers a diverse selection of figures for teams and mainstays are covered too(spidey and ironman).
