Hey everyone!  Trying out another Mecha'thun deck.  This is similar to my other Supreme Mecha'thun deck except it runs 2 Plague of Flames instead of Bloodbloom and Cataclysm.  The second Plague of Flames can be used to help clear the board (whereas Bloodbloom doesn't do much for you early....unless you run Twisting Nether or another high cost spell).

The downside is you have to clear your hand before you can win.  This means you have to play both Plot Twists unless Hemet, Jungle Hunter burns them for you.

So, similar to the other deck you want to acquire one Plague of Flames (instead of Bloodbloom) in your hand.  Then play Hemet, Jungle Hunter to thin out the deck.  Play Emperor Thaurissan (after all of your Plot Twists are gone).  This will reduce Plague of Flames to 0 mana.  Then empty your hand and deck except for Mecha'thun and Plague of Flames.  Then play those two cards to win.

We may need to tech in other cards to make this better.  I'm not even sure the quest is necessary here.  In general, I try to play Plot Twist as soon as I have a good amount of cards in my hand.  This is to try to complete the quest as soon as possible.  If you draw Mecha'thun or a Plague of Flames for 0 mana, you will not have to rely on Emperor Thaurissan to reduce mana for you. 

I do think the quest is not bad because once you complete it, you can draw cards faster (and you don't take damage for using HP Tome of Origination).  Plus the cards cost 0 mana, so again you can get the cards out of your hand faster too.

I hope this makes sense.  I'm not sure if this is any good, but I'll keep trying.  Thanks for looking.

UPDATE -

- Galvanizer, + Mortal Coil

So the original idea had Galvanizer instead of Emperor Thaurissan to reduce your combo.  They both aren't needed although he's a good replacement if you don't have Emperor Thaurissan.

You could run Zilliax, Twisting Nether, Treachery, or another tech card in that slot.

Remember that with this version you will have to use both Sacrificial Pacts (unless Hemet, Jungle Hunter burns them).  So I try to keep a cheap demon in my hand to get rid of them if nec.  Use Sense Demons to draw you Worthless Imps when you have no more demons in your deck.

Good Luck!
