Mirror Kirby is best at deflecting attacks~
The Hammer ability was pretty cool, too. Like, OP cool. The flame hammer attack was like using a smash attack in Super Smash Bros. You're vulnerable for a moment, but the payoff is sooo worth it. So much damage in such short time~
Also really liked the Spark and Freeze abilities in Canvas Curse. Because electricity; and the freeze ability makes you glide super smoothly, icing everything (except the spike balls and other spikes, cannons, etc. :T)
