As someone who plays a bit of Unlimited analyzing Modified right now, I don't see variation, I see a pair of archetypes with a few different variations: Turbo Stage2 and Toolbox. The best examples right now are Empoleon (or GG) and Eeveelution, but there really isn't a lot else in the format. Just turbo [whatever], with Eeveelution being a more flexible variation of it...
It really has changed since the old days where there were 3-4 distinct types (haymakers, stalls, turbo evolutions such as rain dance, and if you call Arcanine or Wiggly type decks distinct too, that goes up to 5)
What's going to make this DP-on format interesting?
