The Combo to this Deck is to play Raza and the DK, then to play Alex, save the two 0 mana dragons, and use them for burst when playing Spawn of Shadows. 

If you play Frizz before Alex comes into your hand you can do a Brann Alex play to give you 4 0 mana cards

Spawn of shadows is 4 mana + 2 pings (from the dragons) = 12 , play silence (if you save it) plus a ping, 7 mana (18 damage), a one mana spell plus a ping 9 mana (24 damage) if you manage to get a small kazakus spell that does 3 damage that's (27 damage) , you can play around with this but the combo potential is there.
