mtg casting exiled cards Narset, Enlightened Exile – COTD Spell Queller · Shadows over

It might well be too narrow for the cube having only really one home but I would still expect it to get more play in constructed decks than it has (which is also none)

Instant Commander (CTRL to add secondary) Artifact Artifact (CTRL to add secondary) Creature Adrix and Nev, Twincasters Ward (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays .) If one or more tokens would be created under your control, twice that many of those tokens are created instead

Extra artifacts like Treasure or Clue keep this commander huge and deadly

Notably, Korvold will benefit from any Magic card type being sacrificed, not just Treasures, so the deck can also use sacrifice-related cards like Sakura-Tribe Elder
