Okay, I've run into a problem. I made 2 more copies of the Archon Warp ability, called one Dark Archon Warp and one Hybrid Archon Warp. High Templars have the High and Hybrid abilities, while Dark Templars have the Dark and Hybrid abilities. (see attached file)
Here's the problem I'm having: If I have the buttons separated on the command card like they are in the file, then...
2 High Templars can use either High or Hybrid warp (should only be able to use High)
2 Dark Templars can use either Dark or Hybrid warp (should only be able to use Dark)
1 HT + 1 DT can only use Hybrid (the way it should be)
The only solution I've found is to hide the button for the hybrid warp under the other High/Dark button, but this means that 1 HT + 1 DT can't merge at all, because the disabled button is still on top.
I've tried making a new Requirement that would hide the button, but haven't been able to find a way to say "2 High Templar are selected"
