Next ARAM champ?

This is my 3rd account. Totally smurfing it out, too. Going to keep it at 5 champs, Im thinking.

Already have:

Sona Garen Gangplank Swain

Im having probs deciding between:

Trundlemonster Teemo EZ Blitz, the raw fist of Riot The Bug that doesn't swallow...KOGMAW! Facelazer Princess, Lux

I want to go Trundle, but having Blitz on shortleash would be quite helpful longterm. I like picking the oddball goodies too.

So...???
