A-Brine Comber

Not yet bracketed (or genuinely unplaceable).

A-Brine Comber is a UW Spirit creature that transforms into Brinebound Gift, an Aura, via Disturb — casting it from the graveyard as an enchantment. This double-faced card fits enchantment-matters and aura-voltron shells, and has Spirit tribal synergy on the front face. The A- prefix indicates this is the Arena-adjusted version, which may have slightly different text than the paper card.
