Theres a page around here somewhere that says the optimal way.

Its something like use commons up to level 15, then uncommons to 25, then rares.

Once you hit around level 25, fusing an uncommon and boosting them to level 15ish is cheaper than using the cards individual. Although, the level increase is probably lower. The minimum any card will give you is 29 XP.

So it depends if you are short on cards or silver.

Using the same alignment helps, but is more of a hinderence because you would have to farm 3 times as many times just to get the same number of cards.
