>>27491955>Here's a flaw with this picture. Previously, there hasn't been a Mega Stone slotThe flaw with the picture is putting the mega stone on the trainer. The trainer holds the keystone, which is what the image should've been displaying.
>If Mega Evolution is postgame only, I doubt they would be handing you out Ampharosite and what not before you're introduced to Mega Stones.You find a mysterious rock (key stone) and figure out what it means over the course of the game. You get some starter Mega Stone later on in the game (Lati@site, Lucarioite) and then the rest open up in the post-game.
