Before the new Mega Charizard cards, the franchise is planning to drop the Mega Brave and Mega Symphonia sets first
Specifically, the wording of Path to the Peak says "Pokemon with a Rule Box in play have no Abilities." However, because the Forest Seal Stone says "the Pokemon it's attached to may use this Ability," rather than it " has this Ability," Path doesn't catch it, because the Pokemon you attach the Stone to doesn't actually have that Ability, it can just use it
While this will make it easier on the rest of your group, if this isnt an investment you can make, you dont have to stress about it
The other Presentation card's location and condition are unknown, making this potentially the only remaining card of its type.
Shown very well in episode 54 where we see Yuri capture Rin and again in episode 75 when he captures Ruri
