In Hearthstone Battlegrounds I rolled E.T.C., Band Manager which allows player to get a Buddy from Tier 2 and onwards. Observation is that the Golden Apostle of Galakrond whose ability is “Battlecry: Replace cards in the Tavern with ones from 2 Tiers higher.” does not in fact give tavern cards from 2 Tier higher. It replaces cards twice and the end result is that the end user (read: me and possibly everyone else) gets card from same tier as they’re currently at, but consistently same tier as currently at.
Observed output:
I am at Tier 3, I play a Golden Apostle of Galakrond card. Cards in tavern gets rerolled once, and then rerolled twice by the engine. I see cards exclusively at Tier 3.
Expected output:
I am at Tier 3, I play a Golden Apostle of Galakrond card. Cards in tavern gets rerolled once. Cards in Tavern should be Tier 5.
