After you renounce the darkness, does it draw cards based on the discounted cost or the normal cost? That is, if you play the card drawn for you, are you left with a single mana?
I've been playing a "Renounce Darkness" lock for fun, which it certainly has been. One drawback is that it could be difficult to get and maintain board presence. I replaced some lock cards with taunts to help, as well as adding Kel'Thuzad as my 8 mana card. Finally, to add to the RNG fun I included Yogg-Saron as my 10 mana card (one of the few non-adventure legendaries I have). Yogg has helped me win a few I shouldn't; at the same time, I've lost a few because instead of going lethal, "madness consumed me" and I dropped Yogg just to see what happens next.One of the challenges is that due to the absolute randomness, you have to be on your toes against your opponent's premade deck. If arena was played where you have no choice in cards, and y ou don't know what's in your deck, it would look like this. If winning is your priority, its probably not the deck for you. If you want a challenge or just want to enjoy a RNG ride, give it a shot.
Trump had a go with Renounce Darkness, it was an epic fail!https://www.youtube.com/watch?v=XHgGvEK8BkUThe whole point of this brawl is the lack of randomness but Renounce Darkness makes it all random which puts you at a severe disadvantage in this brawl. There's very little synergy with any of your plays.
