YOU ARE NOT PREPARED!

This is a little idea that came to my mind earlier this day. Goal of this deck is to hit your opponent for 40 in one turn with your hero power from Metamorphosis while having Clockwork Automaton and Garrison Commander on your board.

To do so, you want to reduce the cost of both of your Clockwork Automaton two times with the help of Galvanizer. Then you need to use Metamorphosis but not the hero power that comes with it. Save it for the combo!

Then, when you have 10 Mana, the 5 dmg hero power and the reduced Clockwork Automatons as well as one Garrison Commander in your hand, play all three cards from your hand (should cost 8 Mana). After that, nuke your unprepared opponent!

How do I survive until then?

Well, you have a ton of card draw in your deck, as well as board clear options like Immolation Aura. Generally, I think the survival part of the deck could be improved in many ways, I'm not an expert in deckbuilding. This particular list is just meant as an inspiration for other OTKs like it. Would love to get your feedback on what to improve. :)
