Forgive me for being a newbie here, but I was curious about something in particular and figured I'd toss it out there. As an Eevee, Sylveon gets the move Trump Card. You know, the move that gets more powerful as its power points go down? With the boost from Pixilate combined STAB it seems like it could do at least a fair bit of damage reliably, but what really makes it shine is how much stronger it gets as its PP goes down. So I was wondering if the attack would be at all viable? Keep in mind at one PP Trump Card's base attack is 190, so factor in STAB plus Pixilate boost...
Hypervoice has a base power of 90, meaning that trump card only damages it on the last PP. No opponent will ever let that happen, since you'll be telegraphing your strategy every time you use it in order to get it down to 1pp. And you only get that one shot, versus 10 (16 PP-maxed) hyper voices.
Also please please PLEASE stop suggesting Moonblast and ESPECIALLY dazzling gleam on sets. Hypervoice is her best move, it goes through subs, and has a 30% boost due to Pixilate which is then STAB'd, and hits both opponents in doubles. And all of this was proven in the battle mechanics thread, so go read it searching for pixilate, areialate, and refridgerate.
Pokebank will be here before you know it, so it's not really necessary to discuss sets that will be outclassed in two months. If you want a defensive set with the chance at a Sp. Attack drop, then maybe MAYBE. But the subs passing of hyper voice still outclasses it.
