Basically after you have completed every single mission and have a few Rarity 3s or Elite 4s that you like, what you do is pick an energon-efficient mission (ones that give good drops and cost less energon).

Any Rarity 1s you get you should sell. Any rarity 2s you use as fodder (sacrifices when u level another card).

If you want to make the most out of a card and get the absolute maximum stats, what you do is:

1) Level both ROBOT and ALTERNATE forms of the card to MAXIMUM LEVEL (20,30, 50 or 65)

2) Transcan both ROBOT and ALTERNATE forms together

3) Level up the Transcanned card to MAXIMUM LEVEL (20,30,50 or 65)
