The moveset potential is there, it's based on the cards.
Arisa: Up b - airbound barrage, leaps into the air and rains down a hail of arrows.
neutral b: entangling vines, charges up and fires an arrow, at full charge, the arrows cause vines to grow on hit plays snaring them into place,
Down b: Aria's whirlwind, surrounds arisa ina whirlwind blowing back enemies and projectiles.
side b: summon roach. Sends a whirlwind rhinoceroach at the opponent, it's very weak and does litlte damage and dies very easily, much like a pikmin but hte gimmick is that it gets stronger each time you use it in the same stock making the opponent want to finish you quickly. There's a cooldown between uses so you can't just spam it to quickly rank it up.
Fox, falco, wolf, captain falcon, villager, wii fit trainer, duck hunt, just to name a few characters with no moveset potential.
