It's a Miracle! Mecha'thun Works!

Built this deck the other night with some promising results (I hope to post stats soon, since I have some technical difficulties with my device.)

The combo for infinite drawing, discounting and healing is straight forward:

1) You drop Test Subject.

2) Then, Radiant Elemental. 

3) Now comes Nazmani Bloodweaver.

Everything is now set:

4) On the Test Subject you apply the following (on that order)

- Embalming Ritual

- Power Word: Shield

- Binding Heal

- Topsy Turvy

With each cycle you draw, you heal, you discount a random card and get your cards back after killing the Test Subject with the Topsy Turvy. 

Once you are ready for the OTK blow, to finish the game:

You drop Mecha'thun => then target it with Voodoo Doll => Finally kill the doll with Holy Smite.

Important Notes:

- You always looking for Test Subject in your opening hand. 

- When theRadiant Elemental is down during the combo, it will not allow Nazmani Bloodweaver to discount Holy Smite. Not that I had problems with it, since usually the Mecha'thun was discounted enough, but just keep that in mind when you want to use the Voodoo Doll option.
