Mono Shadow deck I use for gauntlet grinding. It's pretty consistent and i enjoy playing it. Just wanna get other people's thoughts. The market isn't concrete. Not really great at building/using a market. Sometimes I like to throw in The Last Word for some sauciness.
Burglarize I can agree with, I just have it in there as a silver-bullet against that gauntlet boss that makes both start with that relic that summons dragons after playing 5 spells. Forget the name. Other than that yea, I never end up bringing it in.
Another Dark Return in the market isn't a bad idea though.
