for example
Drogon
Creature Dragon, Cost 6, STR 5
No attachments. Drogon cannot be killed.
etc etc
Someone attacks me (military) with 6 STR. I defend with Drogon. I have another card (Bringer of Gifts) in play.
I lose the challenge, and now I have to choose someone to satisfy the military claim.
Can I choose Drogon and he essentially "saves" himself?
Or am I not allowed to choose Drogon because he "cannot be killed" ... and I'm forced to choose Bringer of Gifts.
Also ... what is the point of the duplicates for Drogon, and cards like:
Black Hatchling
Creature. Dragon. Cost 1, STR 1
No attachments. After Black Hatchling or Drogon comes into play under your control, attach Black Hatchling and its duplicates to Drogon as duplicates, if able.
Is it just in case a card that blanks-out the text box comes up, and by blanking out the text box, Drogon can be killed ... which would make the hatchlings useful to save him?
