[Mill] Dude Where's My Deck

PRO: This deck makes your opponents question reality as they watch their deck fly across the screen into the void
PRO: As SPJ, we have access to the best removal in the game
CON: The removal package isn't optimized
CON: The mana base isn't optimized

So I've been working on this deck since Defiance's release trying to find the best home for Mournful Deathcap. The shell is built around the strategy of finding, protecting, and amplifying this card. 3x copies in the main with one in the market gives you 7 draws (will likely sub out Kerendon Merchant for a Black Market later) that give access to Mournful Deathcap. Unseal and Dark Return help protect Mournful Deathcap from removal and spell-based silence effects. For force-multipliers, we run 3x Mirror Image and 2x Marshal Ironthorn which gets us additional mill triggers. Lastly, we finish our opponent's deck with Solitude. As we're Shadow, Justice, Primal, we have access to some of the best removal in the game. A bonus, too, that Mournful Deathcap is 4-health creature surviving Hailstorm.

The deck is far from optimal and as I build up dust to afford options to check out I'll update the deck.
