Ashiok, Nightmare Weaver mills three every turn and lets you cast exiled creatures for free — that's a repeatable threat engine on a three-mana planeswalker. The catch is a minus-X that nukes all exiled cards to clear opponents' graveyards, which means Ashiok pulls double duty in mill and hate strategies, and Umbris, Fear Manifest decks treat it as a core piece.
Best Commanders
Commanders with the highest synergy
Umbris, Fear Manifest
Every card Ashiok, Nightmare Weaver exiles triggers Umbris, Fear Manifest's power-and-toughness pump, so each activation is both a mill threat and a grow-your-commander effect — the synergy is direct and stackable.
Tasha, the Witch Queen
Tasha, the Witch Queen rewards you for casting spells from opponents' libraries, and Ashiok, Nightmare Weaver's plus ability exiles those cards and lets you cast them — the two effectively share an engine.

In Commander, Ashiok, Nightmare Weaver slots cleanly into mill, exile-matters, and Dimir control builds — three opponents means thirty cards exiled before the first cycle is done, and the free-cast ability can steal a game-ending threat off any library. In Pioneer and Modern, Ashiok competes in a crowded planeswalker field and sees fringe sideboard use as graveyard hate that also pressures opponents, though three mana is a real cost in faster formats. Legacy and Vintage give it legal status but almost no practical home — the effect is too slow and narrow for those environments. Oathbreaker is the other Commander-adjacent format where Ashiok, Nightmare Weaver can be either commander or signature spell, and mill-as-win-condition is more viable in the smaller 20-life format.
