Yeah I think she might be a transform support, considering that the curious changelings is a transform card and have similar magic vibes to neeko I later also noticed the fire blobs in the background, which probably means milio is being added as well. This begs the question of how they are going to put 3 shurimans (I think nidalee is hinted in the other artwork?) in the same expansion (well technically ixtali but still). Maybe shurima nidalee, runeterra milio and bandle neeko?
