You have three right - Punch/Counterpunch and Doubledealer are right. Also, Armada/Cybertron Sideways counts as one (because of the rule that they must be different toys - recolours or international versions of the same toy don't count.) Similarly, because Cybertron Jetfire and Sky Shadow are the same toy, only one of them counts - for example Cybertron Sky Shadow would need to have both a Decepticon insignia and an Autobot symbol somewhere. Does he? (I sold mine at the 2006 Oz Toy Con, but I'm pretty sure he just has a Decepticon symbol.)
There are five more answers needed until someone wins...
Edit: Sorry Trunks - yes Armada and Cybertron Sideways both count (I was thinking Armada Sideways and Energon Rapid Run, because I always think of the Cybertron one as Galaxy Force Noisemaze [since that's the version I had]. Oops. So you actually have four right.)
