so, have all GX's been revealed for this set? I honestly cant remember XD, if they haven't, I think that this is a solid set to release a Flareon-GX, and it also seems like a pattern with Eevee-evolution GX in the Sun/Moon sets-
SM Base- Espeon & Umbreon
SM Guardians Rising- Sylveon
SM Burning Shadows- nothing
SM Crimson Invasion- nothing
SM Ultra Prism- Glaceon & Leafeon
SM Forbidden Light (or SM 7)- Flareon maybe?
Basically, what I have come up with is this pattern, the first set releases two cards, the second set one card, the third and fourth none, while the fifth set contains two cards, and the sixth set (or probably seventh) will contain one card, then once again, skip two sets, and release the last two cards, if anyone understood that at all... lol, if you did, let me know if this is something possibly practical or I am just rambling
