Embarrassing loss

Got my butt absolutely blasted in the Legend Anthology event by this deck. He used the Speedroid cards to make the lvl 3 synchro, activated the synchro's effect to summon the other two, summoned the Wheelder from hand, overlaid for the XYZ, and equipped Psychic Blade. I was on earth machine - he walked over my Super Dora and Anger Knuckle and swung for game. Pretty funny!
