Trigger: Use Kyra's Improved Heal
I noticed that Kyra's Improved Heal wasn't showing the animation for cards flying from her discard pile to get deck, then I realised that the number of cards in her deck wasn't increasing - so the heal had no effect other than to discard a card with the Devine trait.
This doesn't happen all the time, so something must be the trigger. I think that the trigger *might* be using a Major Cure spell during Merisiel's turn. Kyra was running low on health due to Necromancer Damage, so when her turn ended I clicked back to Kyra to check whether her Major Cure had come up yet, it had, so I used it. Next time it was Kyra's turn, the first thing I did was Improved Heal (can't remember the discarded card, possibly Swipe). From this point on her IH didn't work.
