Battle Types:

Battle Arena - Sword - Just spam charge up attacks and throw opponents to other opponents. At one point you will be forced to use fighter, use Y Attacks

Crazy Theater - Doesn't matter but suggested you use Whip in order to command grab opponent - You can save a small amount of time when you win, if you make sure no other Kirby wins, as if they do they will gain a point before you win

Rocket Rumble - Try to make sure the other opponents and you have as little as possible, so the rockets don't fly as far. Every 2 points is 1 second lost. Keep attacking other Rockets and even try using Bombs on your own ships in co-op missions.

Robo Bonkers - Sword / Hammer - Hammer is the faster one but because of the long charge time and how vulnerable you are it is suggested you use Sword. When you're trying to put missiles in the cannon, don't attack opponents. Spam charge attacks when Bonkers is down

Ore Express - You can save frames by having as little as possible by the time the 2nd score board shows up, keep attacking opponents to make sure less ores are given, then try and get as many as possible in the 3rd section

Flagball - Whip - Try to command grab your opponents and throw them into each other to prevent them from taking the ball. If your partner has the ball try getting the flag. If you are behind your partner when a round starts, it might be a good idea to jump up to a higher level as that's where your opponent can jump up to.

For the other battles you can not save or waste any time so use whichever ability you want
