I've had many favourite decks over the years, including quite a few that I know people would hate me for - Original Res Priest, Original Freeze Mage - but I have to say that the very first builds of Cubelock back when Kobolds and Catacombs released were some of my favourite games of Warlock I've ever played.

Admittedly, a lot of that is because the deck was far too good - collectively it's had two nerfs and two Hall of Fame rotations, though I don't think it can be blamed for Mountain Giant and Doomguard - but it always felt like the perfect tension of playing Warlock and messing with your Health and handsize, without ever having to actually worry about overdoing it and losing the game.

The deck is of course defined by - and named for - Carnivorous Cube, which combined well with the various mana-cheating cards in the deck to create massive boards that the opponent couldn't easily clear with a single card. Especially potent for this was Dark Pact, which not only killed your Cube for an immediate minion doubling (and protection against Silence effects) but also healed you for a massive 8 Health before the nerf, allowing you to use your life aggressively and take full advantage of Lesser Amethyst Spellstone.

My absolute favourite card in the deck, however, is Spiritsinger Umbra. Her ability to cause a board state to swing from near empty to overflowing when combined with Cube was amazing to watch, and the incidental bonuses she provided to cards like Voidlord or the occasional inclusion of Plated Beetle made her a real powerhouse.

Plus, y'know, she's a Tortollan. That alone makes her worth it!
