This is a speedy deck that wins by attacking with a nice 20/20 indestructible and flying creature on turn 3. If everything works out, that is.I doubt I'm the first to attempt this, but I wanted to share my brew. Too bad Dark Depths are banned for Modern ;)
The main interaction is Dark Depths + Vampire Hexmage
, for the obvious reason that the Hexmage instantly turns the land into our finisher creature.The earliest that can happen is on turn 2, if you drew the Depths, the Hexmage and a Urborg, Tomb of Yawgmoth, which allows you to tap the Depths for black mana.
Having said that, there's the problem of getting to both cards in due time. The most important tool, I feel, is
Into the North
, which conveniently searches our Dark Depths and puts them on the battlefield. If instead you're missing the second swamp to play the HExmage, search for a Snow-Covered Swamp instead.Satyr Wayfinder is excellent chump-block material and will search a small portion of the library for either a Depths or another land if you already got one. It also often does the additional damage that you need if an opponent gained life in the first few turns.The bigger problem is getting to the Hexmage, and the best solution here is to mulligan until you find one really. Alternatively, with a Wayfinder and
Postmortem Lunge
, you may be lucky enough to put her into play directly from the graveyard.
A few tool cards help in off situations - putting a Lightning Greaves on the battlefield in an otherwise wasted turn can make for a single-turn kill later on that your opponent won't see coming.Add a good amount of removal and Thoughtseize to screw your opponents up and make way for Marit Lage, and hopefully beat them before they can play that Blood Moon...
Complete sideboard will follow, suggestions are very welcome!
