The goal of this Hearthstone Standard Priest OTK combo deck is to use Kael'thas Sunstrider combined with Test Subject and Auchenai Phantasm!

We do this by playing Kael'thas Sunstrider, Test Subject, double Regenerate, Vivid Nightmare, Topsy Turvy, (repeat the cycle as needed), Auchenai Phantasm, and send the Regenerates to the opponent's face!

Challenging, but fun meme deck! Good luck!
