Here is a deck that I've had a ton of success with on ladder.
The deck centres around Hobgoblin and Sword of Justice. With one of each on the board both trigger when a minion of 1 attack is summoned giving that minion +3/+3 stats. The tempo advantage is hard to deny.
Deck is susceptible to board clear and must play around that by keeping a fresh stock of minions in hand in case of a wipe.
Avenge x 2 : excellent secret to trigger Secret Keeper and to help boost small minions.
Blessing of Wisdom x 2 : added to increase card draw as the deck consistently has the ability to empty it's hand. Excellent when played on an Echoing Ooze or a Flying Machine.
Noble Sacrifice x 2 : an auto-include in any Pally deck and it pulls it's weight here.
Goldshire Footman : added to help protect Hobgoblin once on board and has been surprisingly effective. May consider adding a second when tweaking.
Secretkeeper x 2 : incredibly cheap and easy to buff minion. Can get to high stats for only 2 mana (play her into a board with Hobgoblin and then a secret and you have a 4/5 for 2 mana).
Annoy-o-tron x 2 : excellent value when buffed, lives up to its namesake.
Echoing Ooze x 2 : if played alongside Hobgoblin you get a 2/3 and two 3/4s for 5 mana, and the possibilities start there. The same play with a Sword of Justice on board produces a 3/4, a 4/5 and a 5/6 for 5 mana!
Master Swordsmith x 2 : another enabler for boosting plus it continues to boost as well.
Sword of Justice x 2 : expensive if you don't have two, but without them the deck is weaker to the point of being unplayable.
Divine Favor x 2 : as you're constantly dumping your hand, it must be steadily replenished.
Acolyte of Pain x 2 : once buffed it produces incredible card advantage and it can effectively trade as well.
Flying Machine x 2 : once buffed it's out of Flamestrike range and easily 2-for-1's.
Hobgoblin x 2 : another expensive but necessary part of the deck. Do not play Hobgoblin without playing at least one 1 attack minion with him, it is a target the turn it hits the board so be sure to get some value out of him on turn one. If the minion(s) he buffs is/are threatening enough they will soak up removal and you can gain more buffs from him next turn.
Hammer of Wrath x 2 : early builds had no cheap removal and needed card draw. This solved both problems with a single card, great value!
Avenging Wrath x 2 : excellent card to play prior to attacking to make favourable trades. The deck strongly benefits from it but this the one epic that can be removed.
Tirion Fordring : excellent finisher, plus the Ashbringer has won me games that I was on the fence of.
