Mega Gardevoir is a Psychic & Fairy type, and has an alright design, really the big difference is that it has a more poofy looking dress, and an amazing shiny. Mega Gardevoir has the ability of Pixilate, to turn the normal type moves into fairy type moves, essentially gaining more stab moves, and got good stat buffs that this can put in the work offensively, while also being able to take hits okay defensively. Overall, Mega Gardevoir is great, and could have very well made my #1 or #2, but at this point in time, I like to use the other two a bit more.
