This is a pretty good strat, but is kind of RNG-y, especially if your Enchanted Pen dies too soon in the fight. Got it done my third try, though, so I do recommend it if you have the pets and are willing to take the chance! =)
The start was pretty much like the explained in article except if you're lucky not to receive crits Enchanted Pen dies when Scars would have little HP left. After Pen's death I used the Broom's Sweep to kill Scars and simultaneously get rid of the undead nasty resurrection ability. Then wind-up + batter + wind-up and finish Little Blue with Manafiend's Soulrush.
I accidentally used Harmonious Porcupette instead of the Spectral one. Didn't notice my mistake until mid-battle when I looked for Powerball. Oops!! So, he kept Tranquility up, used Moonfire on CD and Clawed the rest of the time. He died at the same time Little Blue died, leaving Broom to claim the victory. Anyone who doesn't have a Spectral Porcupette might want to try Harmonious.
