The Grim Patron created one of the strongest decks Hearthstone has ever seen in constructed play. Though this combo-dependent deck is great in constructed, the card itself is pretty bad in the arena, because of it’s combo-dependency. In my last arena run, I saw the Grim Patron 2-3 times. And in this 7-3 game, it actually worked.
And just for some perspective, this is the first Warrior to beat me in the TGT era. Stick to your strengths!
