He will save us all!
Summon: "Not again!"
Summon: "I. Gamon. Will save us!"
Summon against Rogue: "Try and pickpocket me now!"
Gamon was Ogrimmar's punching bag, up until Blizzard patched him to become a high-level Elite. If you drop him turn 2, not a lot of things can remove him instantly. You either sit there until you can deal with Gamon Elite the turn it comes up or get stalled.
Everyone loves bullying Gamon, including YOU! Mage's Hero Power, Inner Rage, Cruel Taskmaster, Whirlwind, etc. A simple ping turns Gamon into a 4/4 Charge. You can also give him attack (Abusive Sergeant, Power Overwhelming, Lance Carrier, etc) and have him ram into a 3/2, turning him into a 4/4 which can attack again.
Some fine turning may be due, but the idea is there.
