I just use one-hit KO moves that are only one-hit KO moves because my Pokemon are so overpowered. Plus, type match-ups help them get that way too. CHARIZARD, USE FIRE BLAST ON THAT Lv. 1 ODDISH! 1-HIT KO! Oh yeah!
Yes, I like picking on Pokemon that are way weaker than mine. Their fault for running into me whilst I am doing donuts for no readily apparent reason.
Also, Jelly. Yes. Horn Drill is one of them. Rarely use it, too few PP.
