The Boomsday Project Guide
Draw a card for each damaged friendly character.
"You won't like me when I'm angry."
Fits perfectly in new Patron enrage deck :
2 mana to draw 2 cards is already pretty decent, but in many scenarios this will be a 2-mana Sprint, a card which usually costs 4 mana and a Preparation. This card is the backbone of Grim Patron Warrior, and will likely end up nerfed to 3 or even 4 mana sometime in the near future. Until then... EVERYONE! GET IN HERE!
I think this card is a sleeper op. Control warrior plays few minions, so no one ever looked at this card twice, but with grim patrons and the possible return of aggro warrior... people will cry for nerfs to this card.
Lots of people seem to identify the minions in the combo of the Patron Warrior deck as the culprits, but your insight/prediction about Battle Rage is spot on.
Kibler recently suggested the same. The problem with Grim Patron is the consistency with which this deck can deal huge amount of burst from hand even with an empty board. The deck can do this regularly because of its efficient card draw provided by battle rage. Currently it is too easy for the deck to gather all of its needed combo pieces. In the past we've seen such efficient card draw engines being nerfed (Starving Buzzard, Auctioneer).
