With Charge changed from 3 mana to 1 mana, the original deck becomes completely unplayable. I figured out another way to play patron warrior in a mixture style.
Manage to survive until you create at least 4 Grim Patrons on board. That's enough to win.
Against midrange (especially Shaman):
Shaman has plenty of ways to deal with your Grim Patrons (Spell damage into Lightning Storm, Spirit Claws, Lightning Bolt, Hex). Don't play the patrons unless you can play Battle Rage to reload your hand in the same turn. You'll need Golden Monkey to win the match.
You have more card draws than usual control decks so that in most cases you draw Golden Monkey earlier than your opponent in warrior mirror match. Your opponent may have used their Brawl to deal with your Grim Patrons already. Take advantage of this and try to make them run out of stream.
