I understand where you're coming from. I won a lot of games with my Weavile and Electivire. Remember when Electivire was the most feared Pokemon ever? Then, things changed and new Pokemon came. New moves, new abilities, etc. As the game changes, you have to change too, I suppose. However, Smogon doesn't determine what a good Pokemon is. I use freakin' Weavile, a "BL" Pokemon. If I were to use it in an official Championship, people would look at me like I'm crazy. However, Weavile sweeps just as good as a Greninja. You learn with experience what you like to use and what's effective. Doing what you want isn't always popular but again, doing the right thing isn't always popular... Again, with experience in Battle Masion and PSS, you'll see what you like.
I think we actually lost because I messed up when Mandibuzz taunted my Klefki. I really should have seen that coming. I messed up, lol.
