It seems counterintuitive, but your older and more valuable cards are safer than your cheaper and newer ones right now
If Mortify just destroyed a creature at instant speed for three mana, it would already be quite strong
Like most Pokmon cards, the value of Roller Skater depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Cosmic Eclipse)
During the second half of the game, the party is split up, and its possible to finish the story without reuniting them
While thats not too exciting, you still need a baseline to compare what a cheap box looks like in practice
