Also, of all players, our local top Junior player (Tristan - the US Nats Champ) showed up at his first BR with Energy Removal 2's in his deck. The deck checker (me I think), failed to catch that error. Not until the 3rd round did we catch it. With or without the cards, Tristan would've won the event. We applied the penalty (which was reduced to a prize loss), but Tristan handled it well, being the top-notched player he is.
What's wrong with Energy Removal 2's?
