Since I play unupped GotPs only I can confirm a lot of weird behaviour regarding the discard:
- AI is often damaged for 13, obviously not having own ghosts in hand (non-time decks);
- AI is damaged for 10/13 discarding non-ghost card w/ hand full of ghosts + this card - just saw it using the nymph triggered precognition. AI discarded holy flash (instead of playing it, sufficient quanta, full hp).
