Hi, just played the new patch with Reno, his buddy says “deathrattle; make your right-most minion golden” but it does not states “for this turn only” or something like that. Please fix all of those simple stuff, you should alredy know to do it about now.
Buffs in Combat are only for the Combat turn unless otherwise stated, an example of this would be the text on Tony Two-Tusk, it calls out that it is a “permanent” Golden.
Hope this helps clear up the issue for you
