Am I thinking correctly that this card functions the same way The Galadhrim’s Greeting does? At first, I was only focused to make it work as an engine for drawing tons of cards, but now I realized that it can actually keep you in Valour mode for a very long period of time. It can reduce your threat by 9, which is pretty awesome for mono leadership decks.
Pillars of the Kings
While your threat is less than 40, reduce the cost to play Pillars of the Kings by 4. Action: Set your threat to 40. If this effect raised your threat, draw a card (draw 4 cards instead if it raised your threat by 10 or more).
