'Sides, Koopacide has been on the Dojo for like forever. Everyone should know about it.
It's no worse than Donkey Kong's grab in the past or Kirby's suicide drop, at any rate. It's only really useful in Stock matches, anyway, because if you're in a Time match setting, your score's not gonna change.
I think there are a ton of ways its more useful. if it hits it hits and thers no way out of it. that makes it alot better than the dk or kirby suicides. how its useful outside of a time match is pretty easy, say youre up by 1, becuase you just killed an enemy in a hardfought battle that leaves you at 170%. they spawn, you eventually koopacide them, level playingfields at 0, 0, with you still up by one, and wasting a bit chunk of time.
I'm not saying that's nice, or even a great tactic, but it could atleast somewhat work.
Nevertheless, boo on bowser.
