Hearthpwn

The main combo is to return two different horsemen in your hand. After that you play them, then you play Garrison Commander and then play another two horsemen to win the game.

Attention! All four horsemen should be different, so keep in mind that you have 25% chance to summon the same horseman when fishing the second one. If you have a Garrison Commander and two Youthful Brewmaster in your hand, you can get two different horsemen at once.

If you have a choice between playing Zola the Gorgon and Youthful Brewmaster for returning a horseman - play Zola. The first reason is that deck has many even card combo, so you will need that 1 mana difference for playing Youthful Brewmaster later. The second reason is that you do not remove horseman from the board, it's very annoying for opponent and you have a 100% chance to summon a different horseman while first is alive.

Deck has classic Paladin board clear combos: Equality + Consecration and Wild Pyromancer + Equality. Keep in mind that after that combos or a Doomsayer you can play less cost Solemn Vigil.

You always try to find Uther of the Ebon Blade and remove another combo cards (because they are useless berfore playing Uther) at mulligan. Search for Doomsayer versus aggro and Aldor Peacekeeper versus Warlock or Shaman to remove Flamewreathed Faceless and Mountain Giant. But do not forget about cards with silence  try to trade a weakened minion, anyway you do not have to hit the face to win the game ;) (So a little tip for you - do not hit an even Warlock's face at all to postpone an appearence of a Hooked Reaver)
