Dimir Terror combines Tolarian Terror's graveyard cost reduction with Sneaky Snacker actually returning itself from the graveyard to the battlefield once they draw a third card in a turn, making Faerie Macabre's discard-to-exile ability doubly relevant: it strips their graveyard to inflate Tolarian Terror's cost and can exile a Sneaky Snacker before it recurs. Mask of Law and Grace gives protection from black, dodging their Snuff Out and Agony Warp entirely. This is a grindy matchup where they'll counter our first threat with Counterspell, so keep multiple hexproof bodies in play rather than overcommitting. Cut slow fixing lands and Sentinel's Eyes for the upgrades.
