Hidden Fates has been officially revealed. It seems the Shiny subset cards use the "SV" number system, which likely means Shiny Version. If this is true, it seems to have 94 shiny cards. The main set list has 68 cards excluding secret rare cards.
Also Shiny Charizard GX, Shiny Lucario GX, Shiny Malamar, Shiny Buzzwole have been revealed from GX Ultra Shiny. Along with other cards from SM10b Sky Legend have been included. It seems that Jessie & James might have a full art card in this set too that is originally included in SM10b Sky Legend.
Also the Moltres, Zapdos & Articuno GX Special Art is a promo, which is going to be featured in the Hidden Fates Elite Trainer Box.
Hidden Fates will release on August 23, 2019.
Will you get the Elite Trainer Box too? Let me know.
It seems like a very good deal to me now with the 10 Hidden Fates packs and the Moltres, Zapdos & Articuno GX Special Art promo.
