Long-horned Barrensky OTK
The only creatures in the deck are Long-Horned Yaks and Barrensky Vermin. So when a Long-Horned Yak dies, it's attack eventually ends up on a Barrensky Vermin in your hand.
Buff the Yaks large, use them to defend your face, and when they finally die, draw the Vermin and play it.
Your opponent won't know what hit them.

(It took about 20 games to get it to work against a human opponent.)
