Cool! That's a pretty neat line-up of characters
The other characters I love using are: Yoshi (I was a Yoshi main for my entire life. The switch to Lucina was pretty recent), Greninja, DK, Mewtwo, Duck Hunt, and I'm starting to love playing Palutena too :3
Corneria is the bomb, dude!! I love that stage! Prism Tower is pretty cool too
Battlefield is my jam. If I had my way, I'd only be playing on that stage every time. I frikking love Battlefield.
