A third Skyla full art will debut as a secret rare in Shiny Star V! The first one released in 2012 and the second one released in 2015.
Shiny Star V releases in Japan next Friday. We should have all its secret rares by Tuesday, so keep checking back!
Update: A clearer photo of the Shiny Star V poster has revealed a better image of Rose. As some people commented, the blurry Fighting-type card is definitely a shiny Galarian Sirfetch’d. The card is still too small to see clearly because it’s small on the poster.
