Finally made it to Mythic! Took four attempts to get that last win. At one point I lost NINE in a row and dropped back a tier. Switched up to a Red/White mid-range deck and made all the ground up.
Of course once I achieved Mythic it was a let-down. I will get one more booster pack, which you earn 1-2 of every day just playing. Decks are either Red aggro or gate-decks so that is boring as all hell.
