Attach the Mask to any of the 3-power creatures here, and you've just created a coven out of White draft commons. Of course, don't forget to hold up mana for your strictly better Collar the Culprit, and maybe consider playing lots of cards to keep shifting between day and night.
Celestus Sanctifier is pretty neat. White doing more card selection is something I always advocated for and a Cleric that can fill the graveyard slots nicely in Orah, Skyclave Hierophant EDH.
Other than that, ehh it's okay. Mostly Limited fodder, the mask seems especially good since one-drop Equipments are good and Equipments that grant evasion are great, but it's still probably Limited fodder.
