Aegislash, IMO, is more of a tank with damage capacity than an actual sweeper-type. It heavily relies on doing king's shield -> attack -> king's shield (or swords dance if you trick people) and if you time your own stat buff move you end up killing aegis before it can do much AND be buffed before the next guy switches in.
But yeah, this is a good gen for ghosts. And dragons. Hell, this is the best gen since 1, design-wise, and the best technically since 3.
