They actually got revealed yesterday in Chinese, so I wanted to wait for the official English versions, but I didn’t notice that those also got shown by the official PlayHearthstone channel. And so, we now know all of the new minions arriving in Patch 23.2 (releasing on Tuesday, May 10).
The final four cards got revealed by Chinese player 小孩无敌 (Kid Invincible). We only have the official versions of regular minions and not triples, but I think it’s safe to assume that goldens just double the stats & effect.
