Depends on the stars of the specials.

1* - best used for perfect evolves or feeding the troop pet. If you have surplus 1* cottonsail/crumblers, use them like 2* specials

2* - use common and rare monsters to get these to ~20+. Once they are 20+, use them to finishing maxing out 3* specials.

3* - max these out (first 20 levels use commons/rares, final 20 levels use lower starred specials) and fuse into combat monsters

This method is fairly efficient for stone usage as well, and you should be able to stockpile stones for perfect evolves easily.
