Dimir Control is entirely blue-black, so Pyroblast and Red Elemental Blast are live against Counterspell, Dispel, Brainstorm, Lorien Revealed, Spellstutter Sprite, Faerie Seer, Ninja of the Deep Hours, and Baleful Strix, making them premium answers that protect our burn spells and kill key blockers/card advantage engines. Highway Robbery and Melded Moxite are value cards that are too slow against a deck planning to grind with Thorn of the Black Rose and removal; we need to be proactive and protect our threats instead. Keep the core burn package intact since this matchup is a race against their removal suite (Snuff Out, Cast Down, Agony Warp).
