I use a slightly modified version of the Labyrinth Builder Deck. It consistently hits 10k damage and 8000 DA unless you're somewhat unlucky, even without glossy cards. If that happens, you can still get the 5k damage bonus for at least 6000 DA.
After 25 matches I had even a prismatic CV but not one freaking E-con. Then I got one for each of the following two matches. So the bottom line is never give up, I guess. ^^"
