There are loads of Tempo Mage decks on ladder right now, I think this is the best Tempo Mage Season 32, Nov 2016, but there are a few cards you can switch out if you want to experiment.
If you’re not feeling lucky then swap Barnes for a Water Elemental.
Mulligan for your Mana Wyrms and cheap removal spells. Cycle as efficiently as possible to dig through your deck and build up those big Flamewaker turns, that’s where the fun is. 🙂
How to Play This Deck
This is a Cheap Mage Deck C’Thun Standard build that is very effective for its cheap cost. C’Thun is a strong win condition, and seeing as you get some of the C’Thun cards for free it’s easy to get started with this deck if you’re a free to play hearthstone player.
It has a lot of value cards, like Acidic Swamp Ooze, which is great in this weapon heavy META. You have hard removal in the form of Polymorph, and some burn in the form of Fireball and Frostbolt.
Mulligan for Mana Wyrm and cheap removal. Then look to curve out with C’Thun buffing minions on your way to turn 10 when you want to be dropping C’Thun.
