Breeding two of the same dragons together will have an decreased chance on pure. (no it's not listed in the breeding system) process. It seem to have an negative result on the random factor. Breeding mirror + mirror will also only result mirror dragons if you hit on an legend slot.

Try Mirror with Wind on an low level. They will have the best chance on pure. Legendary and Crystal have an to high earning value and since pure is located in dificulty 2 your chance would just decrease when doing an attempt to increase your rating or using an breeding boost.
