Yeah, I really liked the design of Mirror and Beam Kirby (since they are the same xD ) Mirror's powers were so good as well, being able to reflect certain weapons. Made doing the RPG style battle easy. And beam I just really liked jumping and shooting down. The other attacks were cool as well : D
Yeah I enjoyed picking up the enemies with beam and shooting them in the air a lot, plus being able to run and gun in the air shooting down! And the charge beam is always great for damage.
