Dimir Midrange plays their own graveyard value pieces like Psychic Frog and Orcish Bowmasters, plus fetchlands for Ashiok, Dream Render to punish. Extirpate is redundant with our maindeck Surgical Extraction but doubles our ability to strip their key threats or answer copies of their own Drown in the Loch and Fatal Push from the yard. This is a mirror-adjacent grind where card advantage and disruption matter more than an extra point of mill speed, so we trim Glimpse the Unthinkable for the second Extirpate.
