which champions have the most spammable abilities?

For some reason im going through a league “phase” where i just like spamming abilities for a lot of damage lol Needless to say, ive been playing a solid amount of cass. who else ahs abilities the are super spammable? I just know of, kathus, cassiopeia, and evelynn. Anyone else that im missing? And since “spammable” can be a subjective word, we’ll just say abilities 3 seconds or under
