Okay listen. I UNDERSTAND THAT THIS INTERACTION DOES NOT WORK. WHAT I AM ASKING IS WHAT WOULD HAVE TO BE CHANGED TO MAKE IT WORK.
Here is another card that has existed in HS:
This is simply a targeted Undatakah effect EXCEPT that it says "gain a COPY of" instead of just "gain." It is still a battlecry, and it also does not transform the Raptor into another minion. What I am saying is that there is a non-keyworded and unexplained difference between "gain" and "gain a copy of" in these two cases, and with respect to deathrattle effects. It seems to me like a distinction without a difference.
If you understand the interaction, then you shouldn't repeatly state how it not works. Then people will stop explaining the correct interaction to you.
Yes, sometimes the wording in Hearthstone makes a distinction without a difference in mechanic. And sometimes they use the same wording and make a distinction nonetheless. In hearthstone, you can never be 100% sure that a card works a certain way before you did not test it on the board. It bugged me too, but I got used to it.
