I think there's also a case for Marshadow. Zeraora is debuting in GO this summer, so it might be too soon to release the shiny for Alola Tour in February. The only other Alola mythical they could use is Marshadow, who still needs a mainline debut.
Thought this was worth mentioning after how Meloetta was handled. Shortly after we got the Home reward, it was announced for Unova Tour.
