I've been playing the Houndoom Mill deck since I first crafted it when Houndoom-EX was released. This includes playing with physical cards at my local league as well as on the PTCGO recently.
This first deck list I use for
Expanded format. On the PTCGO my record is 33 wins, 15 losses. As you would expect on the PTCGO this is against a mix of competitive and non-meta decks, but overall I'd say it fairs quite well in most match-ups.

This next deck listed below I use for
Standard format. Tbh, I haven't played this deck much since the standard rotation in September. This is my first iteration of the deck in standard and it definitely hasn't been optimized for current standard play. I'd wager it requires quite a bit of revision. My PTCGO record is 6 wins, 7 losses. Not impressive, but to be fair it's quite a small sample size. The main issues when converting the deck to the new standard format was finding replacements for AZ, Xerosic, Super Scoop Up, and Startling Megaphone. Having not really looked at this list much recently, if I were to make changes now I'd probably try the following: -1 Team Rocket's Handiwork, -1 Max Elixir, +2 Escape Rope, -1 Professor Birch's Observations, +1 Shauna or N. Other options to consider would be Exp. Share in order to retain the limited energy in the deck, Brock's Grit in order to reacquire some of those energy and pokemon you'll inevitably lose throughout the match, Hex Maniac to shut down turn 1-2 Hoopa-EX/Shaymin-EX, or even Captivating Pokepuff for the same reason as Hex Maniac, and Ninja Boy to switch out your active Shaymin or to replace your Bunnelby with a high HP Houndoom-EX.
