I can clearly remember the 2 most recent times the best (as they happened like, an hour ago).
The 1st time I think I got Houndoom up with hard charm 1st turn, and got flare grunts.
I started 2nd, with a Houndoom and Shaymin in hand. I attached fire, played a head ringer to the opponent’s shaymin, maybe a trick shovel or two? They got KO’s on a Houndoom, but Xerosic let me discard the 3rd DCE. The other 2 were discarded by attacking. Bats got damage on Houndoom, and I think I flipped tails on 3 SSU’s. Yipee. I used the 1st attack of Houndoom, discarded a water and something else. After my opponent didn’t really play anything, I milled with the attack again. Discarded the 4th DCE, opponent conceded.
This was the same guy as the 2nd win, he wanted a rematch. I think I stated with 2 bunnelby? I powered 1 up (going 2nd again), and milled. They got a DCE on toad, and a golbat on a previously played zubat. Bunnelby went down. Then I put up the other one, played an energy, and flare grunted. And then the next turn flare grunted again. By this point, I had a houndoom down (thanks to a shaymin or two). I head ringer-ed his shaymin the next turn, because he didn’t quaking punch because of lack of DCE. He/she might have attached a water energy. I lysandre-d up his Shaymin, and played an Aqua’s secret base. After 2 turns of me milling with attacks and trick shovels, and he not getting the switch, I had discarded 2 DCE. Those were the last two. We knew I had won, so we chatted for a little.
Note: I totally don’t remember everything perfectly, and my report may not be 100% accurate. I did the best I could
How I won in a nutshell: Discarded DCE with Xerosic, Flare Grunt, milling attacks
