Forum:Dark Room of Nightmare

well i have a fire based deck with crap loads of stall and burn, but i was looking through my deck and I playing Dark Room of Nightmare, activating Backfire before suiciding my UFO Turtles to get out 2 Solar Flare Dragons in like my second or third turn. SO my question basically is; since Dark Room of Nightmare is out, they loose 300 for each UFO Turtle and since I have 2 Solar Flare Dragons out do they loose 300, or 300 each? I also use King Pyron, Fire Trooper, and Volcanic Scattershots too.
