A-Binding Geist

Not yet bracketed (or genuinely unplaceable).

A-Binding Geist is a blue Spirit creature that transforms via Disturb into A-Spectral Binding, an Aura that likely locks down an enchanted creature. The Disturb mechanic allows it to be cast from the graveyard as an Aura, giving it graveyard recursion value in spirit-tribal and aura-voltron shells. Fringe tier due to limited power level and narrow application in Brawl.
