I am at 34 packs, almost a booster box. I pulled four mythics out of these packs.
The Elbrus was the only mythic left over from the redemptions.
The EV was good in this selection:
Falkenrath Aristocrat $4.53
Grafdigger's Cage 3x $4.14
Vorapede $1.54
Drogskol Reaver $0.95
And this EV is not counting the other 504 cards!
