What is Flameblade Adept's Power?
Hi,
Thanks for your question. Discarding a card doesn't care if some other replacement effect changes where the card ended up (hence why a card with madness being discarded will still trigger things that trigger when you discard a card, even though the card with madness ends up in exile). Even with a Rest in Peace in play, the cards discarded by the Lore are discarded (they just end up in exile instead of the graveyard), so the Adept's ability will trigger three times, since three cards were discarded.
Thanks,
Nathan Long
