The name of the game is to slap Dichro's Ruin on an opponent and then force symmetrical card draw, while using cards such as Equalize to keep the field clear of units.
Gatecrash Trooper is rarely going to be a unit you play onto the field. It's best use is as a card to place in the market and then redraw once dichro's ruin is in play or as a plunder/discard option.

Nice take. I tried a take on this with mostly the same cards a week or so ago. Does quite well. Seen a few other versions out there was well. Hurts if Dichro's Ruin isn't drawn early or fails to land.
