i saw a dark nexus skin in a match before and googled that it was an event back in april with deathwing, tassadar and some other skin

will they return at some point? i can see guldan and alarak’s dark nexus skin but not these ones in the shop

bit of a late response, but if you haven’t found out yet, the dark nexus skins for deathwing, tassadar, and fenix, should return next lunar event which if im correct is in february
