Not to mention the spellbook points cost to include three Fireballs : 18 sbp's.
Yeah, at 6 points a piece they're pretty dear. That's why I'm not suggesting 4.
Then again, my idea of a beautiful spellbook is Priestess playing Dire Wolves and Deathlock, or Forcemaster playing Steelclaw Grizzly, so your mileage may vary.
More seriously, Agro books aren't played for the long game. All those carefully horded spellbook points should be spent as fast as possible instead. You lose the long game to Gate to Voltari or Lair anyway.
Other than that I really liked your scheme, going in with an unenchanted Cervere is new to me. I usually cast Cervere on R1 so he'll have at least 1 or more enchantments on him by the time he strikes but your opening might be interesting to use vs ... a Necromancer for instance ?
Necro, Priestess, Swarm Beastmaster, Core Wizard, any druid that doesn't play Vine Tree on turn one (though I might try for double Fox instead of Fox pet), Anyone whose first turn play is double Mana Crystal (except Wizard's Tower Wizard, so none of them). Any newish player who hasn't seen a Round Three agro book yet, etc.
And I'd be more likely to play this opening if I got even polarity. I wouldn't want to try this against Druid that can cast and reveal Barkskin during the QC on round 4, for instance. Of course if my opponent has a habit of leaving enchantments face down till the last possible minute, I might bring Seeking Dispel and forgo my personal attack for a round....
It looks streamlined and terrifying (it is), but there's lots of subtle decisions to make. Force Push + Wall of Thorns is a great threat to have (10 dice, ouch) but it's useless against a well armored mage, especially Vet Belt. Is it worth including? If you include it, do you ever intend to try for it? And so on.
