Hey, happy you liked it! I swapped back and forth between the two from rank 5 to Legend, depending on which decks I ran into. When I saw a lot of Miracle Priest and Burn Mage I switched to Anti-Control, when facing lots of Aggro Druid and Pirate Warrior I switched to Anti-Aggro.

He is just a 1 mana 1/3 in this deck, yes. You could replace him with for example a second Abusive Sergeant or a Young Priestess, but this list is already weak to whirlwind effects, and the Imp helps against that.
