Scout Class

* Dead End
* Dirt Boss
* Knock Out
* Rollbar
* Ransack
* Depthcharge

Deluxe Class

* Bumblebee
* Soundwave
* Breakaway
* Rampage

* Sideways

* Deep Desert Brawl
* Smokescreen


Voyager Class

* Optimus Prime
* Starscream
* Megatron
* Mixmaster

Leader Class

It was bizarre and awesome. Took everything in my power not to just buy everything right then and there :P
