Umbris by grackys

Format: Commander

Commander: Umbris, Fear Manifest

Bracket: 3

Deck overview

Dimir Horror/Nightmare deck centered on Umbris, Fear Manifest as an ever-growing, evasive beater. The primary plan is to mill and exile opponents' libraries with Horror ETBs, Ashiok planeswalkers, and mass-exile sorceries, then win through 21 commander damage. Secondary paths include a one-player mill combo (Fraying Sanity + kicked Maddening Cacophony) and a value-control late game with Captain N'ghathrod, Toxrill, Hullbreaker Horror, and Mind Flayer to steal or wipe. There is no true hidden commander; Thing in the Ice // Awoken Horror is a secondary reset. Cheap counters, removal, and skulk/menace creatures buy time while the deck assembles its exile count.
