I went 2-2 in a tournament today before dropping. I was rocking Mono Black with a makeshift sideboard and I kinda paid for some sloppy play. I got matched up with Elves twice, Death & Taxes, and Imperial Taxes. I really had issues with 2 toughness creatures today as Engineered Plague and Night of Souls' Betrayal were good just not against Deathrite and Stoneforge. How do the Mono Black players board against D&T? I was taking out Sinkhole and I feel like that might have been a mistake.
