The goal of this deck is to use Clockwork Automaton/Velen to OTK as a Shadowform Priest!
There are a number of ways to discount these cards!
With both Clockwork in hand we can Galvanizer, Galvanizer, Barista, and replay both Galvanizer the following turn. Each Clockwork now is 1 mana!
Play Clock, Clock, Vivid, Vivid, Hero Power! Boom OTK!
Additionally, we can use Jepetto/Spirit of the Dead to reduce the combo pieces!
Challenging, but fun!
Good luck!
