Dimir Control plays no red cards but is heavily blue with Counterspell, Spellstutter Sprite, Dispel, Lorien Revealed, and Brainstorm, so Red Elemental Blast is live against most of its interaction and card draw. First Day of Class is cut since games here go long and are decided by resolving a storm turn through counterspells rather than needing haste on the Elemental token. Seize the Storm, Desperate Ritual, Seething Song, and Manamorphose all stay since the plan is still to assemble a big graveyard and make a huge trampling token that can push through Baleful Strix and Thorn of the Black Rose blockers.
