I read through the forums, didn’t find the answer to this, so I’ll start a new thread.
When you ascend a troop, it goes up a rarity level. Rare to Ultra-Rare, Common to Rare, etc. When you use a gold key, you can only get Common or Rare troops.
So if you ascend a Rare troop, making it now an Ultra-Rare, can you still get more of those troops with a gold key? Or does your game version now view it as Ultra-Rare, meaning you can only get it with a glory key?
