Playing Renounce Darkness
There were a few fun cards released with the Whispers of the Old Gods rollout, and Renounce Darkness is one of the most fun and interesting for sure. The card text reads:
Replace your hero power and Warlock cards with another class’s. The cards cost (1) less.
This list is the Trump Renounce Darkness Warlock Deck. It’s similar to some other builds I’ve played with and is a decent deck. You have to accept the fact that there is a huge RNG factor to playing Renounce Darkness.
The benefit is that all your new cards cost one less mana. So you have the chance to play ahead of curve slightly. This can give you a tempo swing, but it’s really in the hands of the RNG gods!
