I was playing as the buddy hero and noticed this bugged interaction when using the Acolyte of Yogg Saron
Acolyte of Yogg Saron → 4 Random Tavern Spells → Knockoff Wisdom Ball → Saloon’s finest
This causes the board to refresh and show all the spells from saloon’s finest. knockoff wisdom ball is unable to activate and any attempt to refresh the board for one gold results in an empty board.
The following turn, you get a full board of minions and a tavern spell on your initial board. Any attempt to refresh the board for one gold results in an empty board. I took a screenshot but cannot attach it here.
