Drown in Sorrow gives -2/-2 to all creatures, sweeping their army of 1/1 Faeries like Faerie Miscreant, Spellstutter Sprite, and Faerie Seer in one shot, which is the single biggest problem this deck presents. Duress proactively strips Counterspell before you commit a key threat, since their whole plan revolves around protecting a small aggressive board with countermagic. Bojuka Bog and Witch's Cottage come out because the tempo loss from entering tapped is too costly against a low-curve tribal aggro deck, and Tithing Blade is weak here since they can simply sacrifice a cheap Faerie. Keep Defile as targeted removal and Crypt Rats as an excellent sweeper against X/1 fliers.
