WOW !!! A huge congrats to Owen T with his back to back GP titles in two wildly different formats. This deck that he used to win the Standard GP was a real beaut to watch him pilot. The true MVP of this deck is a card that most held as an overpowered limited card, but not a huge constructed powerhouse. Owen showed how crazy Pack Rat can really play. A typical opening of turn one Thoughtseize into turn two Pack Rat often meant you were going to face down a plethora of rats in the next few turns, and activating Mutavaults buffs them as they are also rats. Not that this was the only line of play as turn three would often see Specter, turn four Demon and then turn five could have a potential 8 devotion Gray Merchant. And the one of Erebos is good for some card advantage but amazing at stopping opponents from regaining lost life, especially in the mirror match from their Gray Merchants. A full set of Underworld Connections makes sure that there is a steady stream of cards flowing to your hands at the cost of some minimal life points. The rest of the deck is a very powerful removal suite with Hero’s Downfall, Devour Flesh, Doom Blade and Ultimate Price to ensure there isn’t heavy resistance against your heavy beaters.
