This has been working really well lately (in albeit the lower ranks, as it's still early in the month). We'll see how well it fares into the higher ranks and then Master. But right now it feels like a good ladder climber. It really enjoys all the extra Power cards, it has good draw power and removal, and it just feels good to play. Crownbreaker and Warden do a ton of damage early in a surprising number of games.
I might work on an Expedition version too. We'll see...
