Hearthpwn

fun to play and satisfying deck, and it doesn't have any unwinnable matchups, but it does rely pretty heavily on Blood Tap 

best synergies/combo : use Dredger Staff , Vicious Bloodworm , Blood Tap , Darkfallen Neophyte , and or Overlord Runthak to buff a Nerubian Swarmguard - then with 7 mana play Brann Bronzebeard before it to summon a board full of giant taunts (protecting a Brann which can then be used for even more value alongside the 20 other battlecry minions in the deck)

important note- even though Gnome Muncher is the most expensive card in the deck, it's insanely strong with some handbuffs, so if you know for sure you're against an aggressive deck, you can keep it in your mulligan so long as you already have Blood Tap , (otherwise just full mulligan for Blood Tap almost always)
