Keep in mind, while I’ve tagged this as a fun deck, and that is it’s primary purpose, I’ve found it to be fairly strong on ladder as well. The large dependency on RNG makes it less consistent than is optimal, though. It’s also a very malleable deck, this is just the list that works for me. I strongly suggest trying it out and making adjustments as you see fit.
The idea is pretty straight forward: control the board with spells (many of which have overload) until the late game. Once you get there, the deck provides several finishers thanks to The Runespear, Snowfury Giant and Arcane Giant. Depending on what you discover, Runespear can be used to build your board with summons, control with damage spells, or even provide lethal with Bloodlust. Finally, Yogg-Saron, Hope's End is a great get-out-of-jail-free-card if you find yourself in a bad position. Sometimes he can even win the game for you, if you’re lucky enough. I ended up throwing in Tunnel Trogg and Totem Golem to give it an extra edge in the early game, and this worked quite well for laddering. That said, some people might find it more fun to run even more spells instead (but will likely have a lower winrate).
