Spell Queller was
precisely what I was referring to.
Mausoleum Wanderer is a flying Spirit Cursecatcher/Judge's Familiar with an extra buff as well.
This deck gives me every reason to play Essence Flux not just for flickery fun, but because it would buff spirits too.
Displace is just a new Ghostly Flicker, too.
Turn Aside, Unsubstantiate, and Convolute look like good spells to replace cards that will be rotating out, as well as Selfless Spirit, Long Road Home, Collective Effort, and Blessed Alliance.
Yeah, this deck is gonna be a blast.
