Talk:Upgrade/@comment-74.174.58.1-20130628220627

I want to upgrade my R4 and R3 cards with others cards without using Transmetals - how do I know which cards in my deck will give my base card the most upgrade level(s)? Example: Optimus Prime level 1 upgrade, if I use Dinobots, any Decepticons cards, etc. would that give me a higher upgrade? If no, how do I know the common cards for any card in my deck?

Thanks
