I feel like this strategy is just about breaking out of the fun level and on the verge of competitiveness in Standard thanks to the slower pace of games. But I am having trouble finding the right attacker. Meloetta seems like the obvious choice thanks to her built in acceleration plus her low HP of 90 meaning she can be grabbed with just a level ball - plus she will have 80 damage on her at most. Also the inclusion of Psychic energy in the deck means Dusknoir can attack if necessary. Oh how I wish the F/P Mewtwo were actually a Fighting type for the Sash..
I've been running either a 2-1-2 line of Dusknoir or a 2-2-2 (so much item lock right now), which strangely means a Stage 2 fighter is not out of the question - since the candies can be doubled up between both lines, and Korrina is such good fighting support.
Some testing with Mamoswine & Gigalith as the main attackers has worked out nicely enough. Mamoswine's ability and healing move work well with the denial of damage tactic, and same with Gigalith. Gallade is a non-runner despite his nice high-damage/low-cost attack since Ralts/Kirlia will die even with a sash. Garchomp is my next line of enquiry.
The deck is slow of course, but thanks to the Sash that doesn't necessarily mean you actually lose any prizes by the time you get set up.

I'm posting this in here rather than the deck garage just because I'd like to hear the opinions on the general strategy, rather than any particular build. I understand there were similar archetypes with Dusknoirs from older sets, but the ability is different and they were before my time. If anyone has experience with those I'd love to hear even general words of wisdom.
Is this something that can become viable in Standard? Or is it just not good enough. Who do you think I should be looking at as my Fighting attacker and are there any pointers or tips you might add.
