You have two Simulacrums and two witchwood pipers are these to dive for Doomsayer?

This deck looks a lot like twitchrarran's Legend FlameWaker mage with some minor differences.  I'm also experimenting with that deck and am also considering adding primordial glyph as you did. I also considered Ice Lance as a way to add more damage to Ray of Frost. I assume you dropped Bloodmage because you don't have him. Completely understandable. The Banana Buffoon kept adding too many cards to my hand so I understand dropping it as you did.  Where I disagree is Witchwood Piper.  Especially now without Thalnos you're cheapest minions are ALWAYS going to be Sorcerer's Apprentice or Mana Cyclone usually whichever you are missing for the combo.  I personally think it's worth the 100 dust.  I would drop Ice Block works well in other decks but here you either have lethal or you don't one turn extra usually won't help.  If you keep the ICE Block I would add a pyroblast or fireball for that next turn lethal after your trap goes off.  I would think this would happen by missing lethal on the one turn kill combo then the opponent responds with board clear or killing you or both.  Rarely will he be able to board clear trigger the ice block and heal enough to escape pyroblast on the same turn.

Still learning the deck but I played it a few times if you have Bloodmage Thalnos or some other cheap spell damage like Cult Sorcerer or Mana Reservoir as a budget option it really boosts that late-game blizzard board clear and fireball face damage. Also, I left out the Derranged Doctor as I always had board control with frost nova, blizzard, etc and didn't need to heal that much.  I'm probably going to Substitute in Pyroblast or Frost Lich Jania. Anyway thanks for sharing your deck man. 

I played a wild flame waker deck for a few years that was based on spell damage minions direct damage and flame waker and finished with Antinidas or Rhonin. Sadly, I accidentally deleted it. This is twitchrarran's version of Flamewaker.  He wrote an excellent guide and video for it here.

I like it. It's I think harder to play than mine was because there is no direct face damage and if you don't pull off the OTK you sometimes run out of cards without finding lethal.  Also, this deck almost depends on having both flame wakers in play at the same time. I uploaded the deck to experiment with it and contrast and compare it to my deck which I intend to rebuild as best I can from memory. First thoughts, It might actually have too much draw,  especially against fatigue and control decks having 10 cards for the emperor to buff is great, burning cards because of mill rogue making you draw 6 is not.  Also, there is no reliable finisher It's expensive but considering Archmage to add lots of fireballs to my hand in case I miss lethal, or Rhonin or even a leeroy.
