Wow - talk about speed upgrading.

I just used 20 Transmetal units to upgrade a lvl1 R3 Optimus Prime - and he jumped all the way to level 42! Seems that instead of putting a bonus on character cards, this is the future when it comes to quickly leveling your cards. It's a cool solution cause it gives the option to power level, or take the 'normal' path and grind away. I'm sure there will be options to buy them in the store very soon...
