The Grim Patron Warrior deck is currently the top deck in the game. It uses weapons, card draw, and Warrior’s defensive abilities to gather cards and survive into the later turns. The deck can then unleash a series of combos on the back of Warsong Commander, Grim Patron, and Frothing Berserker that can destroy the opponents board and/or health total. Survivability was initially an issue, but thanks to the addition of Armorsmith the deck is now even more reliable. The combos the Warrior unleashes would not be possible without cards like Whirlwind, Death's Bite, and Unstable Ghoul.
Season 18 (TGT) Update
In the aftermath of TGT we’ve seen Patron Warrior get a bit more defensive with the addition of Shield Block. If you go with two Shield Block then you’ll generally want to add a Shield Slam to the deck. Fiery War Axe, Gnomish Inventor, and Unstable Ghoul are the cards of choice to cut when pruning down the list. Cruel Taskmaster is also a card that has seen less play, either being added as a one of or being cut completely.
Grim Patron Warrior Tech Cards
Harrison Jones is good against Hunter and the mirror match up. Shield Block is sometimes used for consistent card draw and survivability. Loot Hoarder can be used for early aggro stoppage and card draw. Slam will sometimes appear in the deck as removal, combo initiator, and/or for the potential card draw. Dread Corsair was in the deck for a while and comes and goes, but it’s a good card to stop aggro and will usually be reduced or free due to Patron’s weapons.
