mtg umbris fear manifest commander deck Umbris, Whenever Umbris or another Nightmare or Horror enters the battlefield under your control The fastest and easiest way

Its one of those decks where even connecting with Griselbrand to go up to eleven life feels good

That makes it useful in just about any white deck, and thats being borne out so far in the new Standard, with the trusty pup being slotted into +1/+1 counter decks, vanilla aggro decks, and even some multicolored ones

Even if the opponent has Leyline of the Void or Rest in Peace that you dont have another answer for, Oko can turn your one- and zero-power creatures into 3/3s, giving your backdoor plan of attacking with horrible creatures some real teeth, especially against an opponent who maybe took too many mulligans to find a hate card

Speaking of a horde of token creatures, thats a perfect use for transforming Westvale Abbey into Ormendahl, Profane Princewho just so happens to be another Demon
