Actual they are if you reset a lvl 1 Sanctify you can have it for free.
After a little search I see Dawn has published that Information yesterday, a bit to late for me.
Would have reset him before I got a Hero with 100% useless Sanctify, guess i can sell the 20 cards left for him.

@g346007_1906957 of course who needs the 12 stars on a hero anyway.
