No one replied to mine yet, someone please do. And yes you can make good combos out of those three.
Off the top of my head...
Attack: Basalt Quetzalcoatl 145 RDF
Defense: Hell Horogium BD145 (Boost Mode) WD
Stamina: Death Kerbecs 125DS
If that is all you might get, I would suggest getting the Hasbro versions of Cyber Pegasis, Counter Leone, and Nightmare Rex because of the Metal Faces and the Metal Wheel Nightmare provides good barrage and Smash attack. I hope this helps!
Also, for a balance type for the Metal Wheel Duo, now this is crucial. Is this the 4D System Duo, or the Hasbro version? With the 4D I would use Duo Orion ED145HF. But, for Hasbro I would use Duo Sagittario 145PD. Hope this helps.

Thanks for the sig, Rock kyoya!
