I was playing Battlegrounds as Malygos. The game had Audience’s Choice twist and a player added a tier 7 Moira Bronzebeard into everyone’s hand. When I played Moira and used Malygos’s Arcane Alteration hero power on Moira, it was replaced with a tier 6 minion instead of a tier 7 minion. I assume it is because tier 7 “did not exist” in that game but that should have not happened nevertheless.
Correct assumption
It has been reported quite long ago now but with no feedback and the anomalies leaving (guessing) next month we can only assume it’s the intended interaction and/or that it won’t be changed
The issue still exists. When you get a Tier 7 minion from a quest and hero power it with Malygos, it becomes a Tier 6.
It should either transform into another T7, or the description of the Hero Power needs to be changed.
