I think might have met a burn deck.
Even it is different deck,but burn deck has same gameplay;throw burn spell at target,at decimate prodigious sorcery for bring back back burn spell with double damage and throw at your opponent face.
My deck is the same,but it has something different
As you can see,it has Library Phoenix,Geminon's Choice,and Inspired Prank.
About Library Phoenix,I use it because Jotun Feast-Caller.
The reason is if you after you use Jotun Feast-Caller third time,your hand might has card that exceed the maximum size hand.
Also,you have no power enough to play a spell and reduce your has size that is not exceeds your maximum hand size.
That make you waste card for nothing.
The phoenix might help to solve this problem.
And don't forget that ,it is reduces non-unit card's cost every card in your hand.
About,Geminon's Choice.I think if you play burn deck,you might a problem about unit that size exceeds the damage you can do.
With Geminon's Choice,It transform the unit into useless unit that easily kill by burn spell in your deck.
About Inspired Prank,I think you might notice that burn deck has many spell card in deck.
That make you can play a big unit in this deck during mid game and late game
Hope you have fun with my deck .
