Stat Raising Moves Are Great. Ones That Lower Your Oppoenets however, are pretty useless. Usually, Its Dumb to bother to raise your stats unless your opponet has more than 1 pokemon. Think about it. Say im Using Scyther. Im battling a Team Rocket Grunt with a Zubat, a Muk, and a Koffing. I Probably cant kill each pokemon in 1 hit, so if I Use Swords Dance, I can 1 HIT KO all of my opponets pokemon with only 1 turn of set up. If Your Opponet has only 1 Pokemon, Usually Raising Your STats is pretty pointless becuase it kinda wastes a turn, asafter using SD, if you can two hit KO the opponet anyway, using sd will be the same as hitting it with 2 attacks. Hope I explained well.
