Hidden Fates: What we know so far

Hidden Fates will come out in August, and it's based on the long-awaited GX Ultra Shiny set that was released in November 2018 in Japan. This set had 250 cards, that consisted of reprints, new cards and 100 secret rare cards, including gold cards and shiny cards..

GX Ultra Shiny had some new cards exclusive to that set, and some have been released in our sets already. What can we expect for Hidden Fates?

Before you read: Please mind that this is speculation, this may not be fully true when Hidden Fates has been released.

Full art Supporters

GX Ultra Shiny had 10 full art Supporter cards, 5 cards are not yet released here;

• Aether Foundation Employee
• Guzma 
• Cynthia (Confirmed to be in Hidden Fates)
• Fisherman 
• Hiker 

It would make sense for them to be in the SV subset since they are most likely going to be alternate art cards. 

Main set list

The main set list has 68 cards. 39 cards of that will be from the Family Pokemon Card Game set. With Mewtwo GX being confirmed.Other confirmed or unreleased cards so far besides the Family Pokemon Card Game.

Giovanni's Exile full art was not included in SM10 Unbroken Bonds. Since Jessie & James has been confirmed for Hidden Fates, there is a high chance the full art version of Jessie & James might come. This could also give Giovanni's Exile a chance to be included in Hidden Fates.
