yeah I don't Iv/ev train, i just level them up. Yeah i need to level him up for evo, i forgot to teach pupitar thunder as a larvitar, but i'll do that as t-tar
you have a good combo there, did you iv/ev train them? my gengar, when it was 25 was faster than a 45 vibrava. My strategy is PupiQuake+LeviGar, it's a great strategy imo.
