Actually Golem is from Legend Maker I believe and it's power lies in the following combo:
Meteor Falls+Enraged Linear Attack
Basically Golem uses Meteor Falls to copy Geodudes self destruct attack doing 50 to the active, 50 to itself and 10 to each benched pokemon. THEN next turn Golem will have at least 50 on it, so you can use Enraged Linear Attack doing 50 to any Pokemon in play OR just use Geodudes attack again and hit w/ Enraged Linear for 100 the next turn.
Castaway, Scott, Cessation Crystal, and Energy Root really shine in this deck getting anything necessary out.
I have seen the deck in action and it is DEADLY.
BUT I have no clue if that's how this guy played it, and the Exploud idea is something new and interesting.
