I think Maestra of the Masquerade looks nutso fun, so here is an idea for putting her in the older Weapon Rogue archetype. This is a stealthy list with Self-Sharpening Sword instead of Swinetusk Shank, and admittedly Shank/Poison Rogue with Maestra is probably a better route. BUT, I like the stealth minions better and want to try out the neutral SI:7 Skulker to get a couple discounts here and there. 

So we're not trying here to trick our opponent deep into the game. The idea is Maestra messes up their mulligan to toss weapon removal or AoE allowing us to smack face. We want 1 drops, Greyheart Sage, and Sword in the mulligan. Build up the weapon, draw with Cutting Class, and finish with Wicked Stab (Rank 1). Garrote with a single Silverleaf Poison is an idea for more draw and some more chip damage. Depending on the meta Steeldancer and Secret Passage could be replacements. 

This deck is for fun. I don't think anyone is hitting #1 legend with it.

Mulligans: 1 drops, 2 drops, Sage, and Sword.

Get 'em.
