Not sure if this is the right thread, but I'm staging a battle against a friend. The plan is to use three level 30 Pokemon, not RNG'd but EVs are allowed. First of all, I'm not sure what to use. I was thinking about Starmie, Drapion, and Snorlax, but I am still unsure. Second, will the EVs be altered due to the levels? (for example, is the basic 4/252/252 spread still usable?).
If you Ev-train on a low level then yes. A Porygon-Z or Porygon2 insteaf of Snorlax is possible too.
You can use a Magnezone too (there are Lv.17 Magnetons in the SafariZone from HG/SS)
