There is no combination that give an 100% chance to get pure. I believe the highest chance was 5%. I bad new that's the % is an lot lower. But here's a hint:

It seems that the pure dragon is listed in the dificulty 2 slots. So you have 1 option since the rating is minimal :
 * Get your rating to 230-299 so your slots are 10-10-2. If you go higher your chance will decrease. This mean your legend dragons have to be level 4. Since your chance decrease when they are higher.

Another note:
 * Legendary + Crystal level 4 =
 * Legendary + Mirror level 4 =
 * Legendary + Wind level 4 =
 * Crystal + Mirror level 4 =
 * Crystal + Wind level 4 = (only wind can be level 5)
 * Mirror + Wind level 4 = (only wind can be level 5)

Funny enouge I could reverse my theory ones I discoverd pure was located into dificulty 2. I known the reason why pure is that hard to breed. Simple because how higher the level, how harder to get him.

With this combo you will have % chance to result an dragon from the dificulty 2 slot and about % to result an pure when he's listed in one of the 10 slots. In total there are 25 dragons listed in that slots (note that you need to remove the other pures first since those can't be result: -3) 45,45% chance that the dragon is listed inside. So the extreem max chance for an pure with this combination is only %.
