My own playstyle? Hell, I don't even know my own playstyle yet. Remember what I said about being a battling novice before joining this? I'm still developing my playing style. I know how to whallop things in-game, and I tend to be an attacker, but an finding after the battle with you that the all-out attack strategy doesn't always work. Sure, I could lead with Mega Tyranitar and set up with a Dragon Dance, then smash something...then another Dragon Dance, and smash again...but that doesn't always work. Especially against something it's not strong against. So I have to think of a way to build status into the all-out attack. Stealth Rock/Spikes control? Healing moves? Build defensive bulk and chip away while staying on my feet? I have no idea yet what my style is, and I'm going to have to work at that.
Of course, if you want to help me with figuring that out and suggest movesets to try after a few League battles, I'm all ears. I can always breed a new one or use EV berries to drain all the EVs (or even a Perilous Soup, obviously that's quicker). The plus will be having it already evolved so any soccer games are quick, or I can try hordes once I figure out which hordes to go after for the EVs (I should make a Google document for that). I know you like hordes, but unless the species drops 3 in a stat, 12-EV soccer games are much faster and not reliant on a certain horde appearing.
