Overall Strategy
The goal is quite simple: use some early disruption and control with Duress, Condemn and Tidehollow Sculler, and put your Hero of Bladehold and Mirran Crusader when the path is clear.
Mulligans
You want to have at least 2 disruption spells, and 1 menace. With 24 lands, don't be afraid with 2 or even 1 land, if you have disruption to back it up.Also, this deck doesn't have a lot of card draw engine, so you should not mulligan too aggresively.
Sideboarding
-Disenchant: Obviously against affinity
-Spectral Procession: When you can go wider than usual
-Timely Reinforcements: Against burn and tokens, this card is really great
-Bojuka Bog: Because dredge is one of the most broken deck in the format
-Despise: Use these instead of Duress if you are against a creature based deck.
Tips
-Tidehollow Sculler seems like a thoughtseize with a body, but prepare to face a lot of hate against it, as your opponent will want to get back his card, so you should not base your game around it.
-You should also remember that Tidehollow Sculler feeds an eventual Tarmogoyf, so don't abuse it against Jund or Abzan Midrange.
-If there is one thing that you want to keep in mind, it's that this deck is really good against spot removal, but wraths are extremely effective, so be aware that your opponent will board them as much as possible.
