-Normal X Super snow :100% mack snow but isn't that big difference to normals in appearance
-Normal X Mack snow: 50% normal, 50%mack snow (same note as above)
-Normal X Enigma: 50% enigma, 50% Normals, but that would be expensive
If you have a budget of $100, and you want a pair. i would say go with tremper albinos, las vegas albinos, patternless, or blizzards.
For the breed normal to non-normal, and get all non-normals, can't really be done with 100% accuracy. Normally a normal will be het for a triat, lets say tremper albino. So if you breed that normall to a tremper albino you would get 50% normal, and 50% tremper albino.
I still think that your best bet would be to go with the morphs that aren't as pricie anymore.
