And then yours is doubled, so I like her as a midrange white Commander leading with ETB stuff like the recursive Sun Titan and card draw in Inspiring Overseer and removal in Loran of the Third Path, and then triggers like Soul Warden and Angelic Chorus
Flavor and tone aside, there are strong mechanics in Duskmourn with manifest dread, survival, and rooms
One unblocked or trampling double striker gives you two extra combats in a Tifa deck, but youre also in good colors for Anzrag, the Quake-Mole or Aggravated Assault
In fact, I dont see why we couldnt build a dedicated blink deck featuring all sorts of creatures that dont mind getting phased out of existence at instant speed
We already play Firebrand Archer in EDH decks that buff damage, and some of those commanders are in Standard, like Ojer Axonil, Deepest Might / Temple of Power, Ob Nixilis, Captive Kingpin, Urabrask / The Great Work, Taii Wakeen, Perfect Shot, Judith, Carnage Connoisseur, and Imodane, the Pyrohammer
Then you only lose 4 starting life, just like Squee above
