Would it be possible for the AI to check for Bad Reaction to Simochi and/or Nurse Reficule the Fallen One before activating Gift Card? (I know there are some other Gift Card inclusive strategies, but they seem a bit too complex for the AI to handle.)
At some point, sure. Not a high priority for now, though. I want to focus mainly on the decks designed for the AI, it is nigh impossible to have the AI play every card in existence correctly anyways.
