If you ever played online, I guess you know why they're there

I use Kirby in smash ultra mite and i spam the hammer alot

Lucas also spams pk fire
all the links are projectile spammers

Im a link main and i dont spam

Lucas' PK fire isn't that spammable & is actually used WAY differently when I played against him online
Toon Link's projectiles aren't that spammable

Do you have the zacian and zamazemta spirits yet?

No

I’d say Kirby is one I use A lot and when I say A LOT I MEAN A LOT

Ah palutena, the spammiest spammer since ness

I tend to spam counterattack and reflect moves.

But they're easily punished so it's not that much of a threat.

Did you know there are Joker mains who spam his down-B?

Yeah, but they're less of a problem since you can punish them easily.
