Ive come up with some basic ideas for decks that would work in 2 vs 2 matches. These are based on cards I have, so...
- Guld Deck + Milla Deck
Idea is for both characters to get 2 Gulds (1 person) and 2 Millas (other person) to power each other up. Add in Bullet Storms, GN Attack and GN Guard cards to power the cards up. Make use of Resist/Wall/Protection to guard each others guns so you can get maximum damage! To help, you could try Shields and Mags if you only have one Milla/Guld.
EDIT:
Dammit! You took the Canadine and Hidoom/Miguim deck idea!
