This is the deck I used to win Dance of Dragons yesterday, the largest North American regional tournament. Play the good cards + play well = win. Play tears of lys, play three of them, every, single, time. I saw even very good players playing absolutely unplayable trash, and yet no one played tears of lys against me the entire day. If you can find room for garbage like isle of ravens, close call and heads on spikes, surely you can make room for a card that is the best kill spell in the game and on the very short list for best card in the game. Or don't, and I'll keep murdering people with 3x Gregor Cleganes. I suppose the choice is yours.
