That was a strange second game in top 4. From what I could tell Benjamin had a Darkrai with about 60hp left that had 3 energies on it plus a dark claw and another one on the bench with no damage or attachments made to it. He then KOd the opposing Zekrom and David promoted a Smeargle which had a DCE on it with SAB in play. He then dropped a Mewtwo and Dynamotored twice onto it and attached a lightning from his hand. He then dropped a Shaymin, instead of moving all energies onto Mewtwo which I was expecting. He moved all the energies, but the Lightning and DCE on Thunderous. Which meant he could knock the active Darkrai by doing 180 damage but only do 120 damage (as opposed to 180) when the next one was promoted in order to win the game. Miraculously, Benjamin catchered an Eel and was able to stall out for 3-4 turns, causing David to deck out.
