7 Doomguards in single turn

Please Test this deck as i dont have much time to play but i did win few matches 

it’s about summoning doomguard attacking then use carnivorous cube 

if you have enough mana kill the cube and get 2 more doomguards 

do not play doom guard use the Skull of the man’ari or use Possessed lackey

and the rest of minions just to delay so the final result is playing gul’dan and getting 7 doomguards

I repeat this deck is not well tested and not sure if good or not. 

i added corpse raiser to give doomguard respawn then kill him with cube
