I haven't heard of the mewtwo ex glitch xD Although once my full art teriakon could attack like the writing on the card full out disappeared including being able to select an attack... another time someone used a catcher against me and I was given the option to cancel the switch :P It's cool knowing someone on smogon whom plays tcgo maybe ill see you in a match some time since thats the only way to battle someone... since mutliplayer doesn't work yet ._.
