Mewtwo with draw

This is a just an updated version of Mewtwo Ex with meowth, but Sigilyph is just strictly better in a psychic deck.

Main strategy is to set up Mewtwo Ex with gardevoir on the bench. This allows you to use psydrive every turn for 150 damage. Lead with Sigilyph and draw until you have everything you need. Ideally you wanna retreat your Sigilyph so your opponent doesn't get a point from it and has to take down both your Mewtwo Ex. You can consider adding a Jynx for a better matchup against Celebi, Charizard and Gyarados.
