Dragon Rage and Sonicboom are banned in that kind of battle if they are Lv.5, but not on Lv. 100.
Voltorb has Sonicboom as basic, and it is the fastest unevolved Pokemon. GG.
Also, level up moves are allowable: breeding passes Lv. up moves if both parents have it.
Overall, it has the same movesets as normal game, but with some differences: Larvitar might be using Fa?ade instead of Crunch because of Guts, Beldum won't see any use, nor will do Magikarp or Feebas, lots of things won't be EQing and such things.
BTW, Meditite and Scyther are uber here. Chansey used to be, but now Happiny is allowed.
