# Aerie Auxiliary Aerie Auxiliary is a common from Modern Horizons 3 that appeals primarily to limited players and casual flyers enthusiasts. The card represents the kind of efficient creature support that defines limited formats, making it relevant for draft and sealed deck builders rather than constructed formats. Collectors tend to view commons from supplemental sets like Modern Horizons 3 with mild interest unless they have exceptional artwork or mechanical significance. Both nonfoil and foil versions exist, though foils command minimal premium at common rarity. For most collectors, Aerie Auxiliary serves as a set filler rather than a sought-after piece, though completionists acquiring full Modern Horizons 3 sets will need both variants.
