The goal of the deck is to keep your opponents board/deck empty and getting your pyroblast discounted to 5 mana with the naga. 

After this you can get a ttk (two turn kill) by playing alex and having pyro + another burn for 5 mana.

The deck struggles against armor gain and healing. 

It's a fun deck to play and seems to be good vs quest shaman.

There are a couple of cards which might need changing so if you have any suggestions, please let me know in the comments below :-)
