This has been my main deck on ladder. When they released Moonstone Vanguard, I had to try and build Praxis Sentinels and the deck over performed initially. And it worked. Sort of. BBG built his own list and that informed some of my decisions for the current list. And then one day, I opened up a copy Zal Chi and Howling Peaks and decided to test the meme. Does playing Howling Peaks (even if poorly and inconsistency) increase your winrate?
Update #1: The deck is still tuning itself out but it's pretty sweet. If you can hit 4-5 power, you're golden. And that's not terribly hard to do which is nice.
Update #2: So far, we're 32-7 with this deck as of right now which is way better than I ever thought I was gonna do. But here we are in the 700's of Masters. Chilling with a silly homebrew deck.
