I finally found my kamek moveset, so yeah. here's my take on it:
Kamek uses his wand for most of his A attacks. Considering that it fires bolts of energy, he may be the only character to have some ranged A attacks.
B Moves:
B, Shape Bolt: Kamek charges his wand for a second, then fires a bolt of rainbow energy. It moves straight ahead fairly slowly, and knocks the opponent into a random direction. It does pretty good damage.
>B, Block Conjure: Kamek waves his wand, and a large yellow block pops into existence in the air a little bit in front of him, then it drops down quickly, doing heavy damage to anyone it hits. It crumbles away when it makes contact with the ground.
^B, Broomstick: Kamek pulls out his broom and flies slowly for about five seconds. You can control his flight direction with the control stick. You can still be attacked while you're on the broom.
Down B, Enlargement Spell: Kamek waves his wand and cackles, then he grows about to the size of Mario's taunt, with increased strength to match that of a Mushroom. He stays like that for about ten seconds, then he can't use the attack again for another thirty seconds. If you try, you get his B instead. Good to use empowering you for the KO.
A Moves:
A: A quick whack of the wand. Lightning shocks the opponent, doing light damage.
Forward A: Kamek swings his wand forward, doing minimal damage but decent knockback if he hits. If not, a small ball of green magic shoots forward, travelling until it hits someone. If it hits, it blows up, shocking them and doing decent damage.
Down A: Kamek makes puffs of air rise from all around him doing light damage and knocking the opponents up, like one of Clefairy's Pokeball attacks in SSBM.
Up A: Kamek lifts a palm and a puff of fire shoots up, doing light damage if it hits.
FSmash: A powerful wand jab, sending out a large ball of green energy. Essentailly a more powerful Forward A.
DSmash: A cascade of lightning appears around Kamek, shocking foes and doing some good damage, but terrible knockback.
USmash: Kamek makes a bolt of lightning shoot out of his wand, going up. Like a weaker, reversed version of Pikachu's Thunder.
Dash Attack: One of his only non-magic attacks. A weak whack of his wand.
Nair: Somewhat like Mewtwo's. White lightning shoots all around his body.
Fair: Kamek holds out a palm, zapping foes with rainbow-coloured energy.
Bair: A backwards kick. Terrible range. Not very strong.
Uair: Kamek claps over his head, and a small explosion shoots from between his hands.
Dair: Kamek shoots four of the shapes from his B downwards. Less powerful, but potentially multiple hits.
Throws:
A: The opponent is zapped by eletrical power.
Forward: Kamek shoots the opponent forward with a fireball.
Back: An overhead toss.
Up: He shoots the opponent up, then fires a Shape Bolt at them.
Down: Like Ness's. Throws the opponent down and zaps them for a few seconds.
Taunt: Kamek adjusts his glasses and cackles.
My concept of Kamek is as a bad jumper and a slow runner. However, his magic attacks are fairly powerful and unpredictable. He's also very good at range, due to having numerous ranged attacks. A Kamek player should try to avoid his opponent, spamming projectiles at him, then use his Down B to become stronger and go in for the KO. Speedy enemies would be a terrible matchup, as they can rush in and take him out, while slow enemies could be kept at bay almost indefinitely with the projectiles. As a magic-user, Kamek would be tricky to use, but lethal if the right combination of magic and projectiles were used.
Yes? No? Eh.
