Their deck has plenty of blue spells: Brainstorm, Ponder, Daze, Force of Will and Wail of the Forgotten. Red Elemental Blast therefore has real targets, so bring it in to counter those spells, especially Force of Will and Daze when we are pushing a key threat or a Blood Moon effect. Also bring in Unlicensed Hearse to fight Hogaak, Arisen Necropolis (delve, convoke and casting from the graveyard) and the Stitcher's Supplier and Moonshadow graveyard synergies by exiling their yard. Trim a couple of Chalice of the Void: it is slower in this matchup, and a Chalice set to 0 would only hit our own Chrome Mox. Shatterskull Smashing is fine against their small creatures, but we have enough removal already, so cut the copies to make room for Red Elemental Blast and the graveyard hate. Keep Fury and Screaming Nemesis in as premium answers to Orcish Bowmasters and their other small creatures.
