How to Play This Deck
Grim Patron is still a viable deck to climb to legend with. The Warsong Commander nerf did little to stop this deck. The fact is that Grim Patron was the problem all along, I think most people knew this before, and after the nerf. This Grim Patron Warrior Deck Old Gods Standard build is proof of this.
There aren’t a lot of changes from the Patron decks of old. Your activators for Patrons include:
Blood to Ichor
Sir Finley Mrrgglton (Mage hero power)
That’s more than enough ways to activate Patrons and start spawning more for infinite value. Once you flood the board with Patrons there are only a few cards in the game that can deal with the board. Learn what these are and play around them where possible.
