You're missing something on your list.
Ness:
PK Flash cancels out Meta Knight's Tornado.
Baseball Bat either knocks Meta Knight out of his Tornado or doesn't affect his Tornado.
PKT2 does nothing to Meta Knight's Tornado. I thought I'd go ahead and point this out in case someone else wanted to try this.
PKT can stop Meta Knight's Tornado if he's hit from above while using his Tornado.
I know some of this is probably useless to you, but it's not like it's impossible.
