It might work
If it doesn't you are getting removal from opponent which is also good.
To make things clear.
No matter what hero power you have, change, improve, change again your cost will remain ZERO. The ability of Raza is like an aura. It remains through the whole game. It's stay's ZERO. The dream. The only problem is MANA CURVE. You need to start playing like a Handlock/renolock. You will want in your deck lots of great trade minions, efficient spells.
Other choices - needs testing
Many choices. As i see it the deck has a chance to be extraordinary good and at the same time extraordinary slow. Will you survive till Mana 8 ?
Time will tell. For 4 months we will have very fun decks. On next rotation we will probably get other fun cards.
This could work
Remember Blizzard's goal is wipe out the gold we earn through quest so we are forced to spend real money.
It's hella playable - example shown was 10 mana deal 6 damage to all enemy minions and summon three friendly minions that died. They said around 100 different combinations for possible spells.
Neutral card reduce weapon costs by 2, use this, starving buzzard attack, draw card, next turn attack, hound master and other things. It has synergy in proper combo. Its a filler combo at 7 mana . . I am afraid midrange hunter got better . Beed to wait and see synergy
If it works like Shadow Madness then you can't silence the mind control effect. In fact it would return it to you opponent instead, admittedly silenced, but not for you.
