This is not a meme deck.
Okay, it is a meme deck, but it's a competitive one. I'm winning more than I'm losing with it. It's also really fun to clock opponents for 20, 30, or 45 damage from hand with a card they've probably never seen before. As early as turn 7.
I've taken the deck from rank 15 to 5 (or better) on all three servers. Very good matchups vs. Warlock, Priest, Rogue, and quest/highlander Mage. Lose hard to Warriors and Paladins and secret Mage. Pretty even matchups against everyone else.
Mulligan for Master's Call and Phase Stalker. Typically keep Candleshot. Depending on the matchup, keep a Wandering Monster (vs. Paladin, Warrior, Shaman, Rogue, Hunter), Tracking (Priest, Warlock), or even Flare (Mage).
This deck really wants to play Master's Call on 3, Phase Stalker + hero power on 4, and Scarlet Webweaver on 6. Depending on the matchup, and whether or not you're on the Coin, either Candleshot, or Coin + Phase Stalker, is your best turn 1.
Turn 5 is a flex turn; if you have Knuckles and Scarlet Webweaver in hand, make sure you've played out your Phase Stalkers, and think about Tracking or Flare to cycle through your deck for Goblin Prank, The Beast Within, or buff cards. Marked Shot can also be used to create these cards.
You can draw through your deck as fast as a other combo decks. Ideally, you want to Master's Call and Phase Stalker before you Track/Flare. (Save one Flare for OTK turn vs Quest Mage.) But Track for Master's Call early if it's your best play on the following turn.
You want to create enough friction on the board to protect your face. It's okay spend some buff cards or combo activators in order to control the board.
The combo turn can be a bit tricky to navigate, if you don't have Bestial Wrath to make Knuckles immune, or if your opponent has annoying deathrattles on board. The board state will dictate whether you can take random attacks (The Beast Within) before your directed attack (Goblin Prank), or whether you need to direct before random, or whether you need to alternate random/direct/random.
Note that if your opponent only has one minion on board, it's still possible to make multiple attacks against it, if you don't fully buff Knuckles for the first attack. Against Resurrect Priest, try to save Unleash the Hounds for the combo turn, so you can create some sacrificial minions for the Priest's deathrattles.
Also, Scarlet Webweaver isn't strictly necessary for an OTK. If you don't find it by turn 10, or it gets ratted out, or whatever, you can still put together lethal damage in many cases without having played it.
Gameplay vs. Secret Mage, Quest Mage and Even Reno Shaman at rank 5. I bet the Shaman, in particular, was surprised...
P.S. If you had any question about the eternal debate over
cavemen vs. astronauts whether Tracking is a good or bad card, this deck should remove all doubt. It's a freaking awesome card.
