Im looking for ways of improving the deck, right know i have a “reduce mana costs” type shell in the deck but looking forward to a better strat.

Also give me feedback on Kalecgos and Puzzle Box of Yogg-Saron if they fit in the deck or something like a   Daring fire-eaterRagnaros the Firelord  would be better

How to play

you want to have Majordomo Executus , Coldarra Drake and Maiden of the Lake in your hand, make your self comfortabel enough with Ice Block to play them.

to reduce their mana costs with Luna's Pocket Galaxy, if dont have luna’s you can try to fetch her with 

Raven Familiar or Tortollan Pilgrim, you can also cast her earlier withNaga Sand Witch or Emperor Thaurissan .

when you’re ready to cast all 3 minions use Conjurer's Calling on domo to turn right after you play them, domo being 9 mana minion will spawn two 9 mana minions on the board from conjurer’s.

And after that just abuse your hero power and have fun with has FIRE LOrD.
