I agree with paradigm72. Swiftspear is terrible late game, but he's the reason for explosive T2s/T3s. He does a great job of getting 6-8 damage in and putting the opponent in range of sealing the game with Price.
With all due respect, 9 rounds is hardly a huge sample size and you didn't even play your last round according to your report. Plus, 4 of your wins came from having PoP against decks that run close to 0 basics. Now, you obviously had success with the deck and that's awesome, but I wouldn't be so quick to cut swiftspear after 1 tournament.
