Grixis Control

Hey there! So I've been away from Magic for quite some time, and have recently come back to it. I am currently running a U/B control list, but with the rotation of grasp of darkness, and the reintroduction of better dual lands, I am considering running a grixis list. It is a jack of all trades control deck, capable of countering, dropping kill spells, and also capable of putting on -1/-1 counters via synergy with Soul-Scar Mage. I believe there is a real chance of doing great with this deck, especially with a sideboard that can gear the deck either more toward the control match-up or more toward an aggro match-up.
