This is the most powerful iteration of Darkest Hour I’ve been able to brew up in standard. Galakrond added a few spells to the list that can create demons to use for Darkest Hour. Also, the addition of a ridiculously underrated card (Alarm-O-Bot) allows the deck to put a lot of pressure out early. Coin + Alarm-O-Bot on turn 2 can win the game if it is left unchecked by cheating any of our big minions out early.
The only downside of this deck currently is that it is quite light on removal. It is already pretty heavy on spells and adding too many will mess with the ratio of Darkest Hour targets.
I’m still adjusting the list a bit for the changes in the meta, but this version of Darkest Hour seems to be the highest win rate I’ve had out of the deck.
