Have you not heard of Coretapper? What of Darksteel Reactor?

It's not ogre til I say it's ogre.

Magus of the Bazaar is way better than Merfolk Looter.

Good sideboard cards:
Extra Ensnaring Bridge and Lilliana
Smallpox (not Victim of Night, ew)
Nihil Spellbomb (to mess with graveyard-based decks like Living End)
Surgical Extraction or Extirpate
Blackmail

Good maindeck cards:
Dark Confidant - not only does nothing cost more than four, you are literally trading card-for-card against every other deck, so Bob is definitely a powerhouse

Bad maindeck cards:
Black Sun's Zenith? Really? A very clunky removal spell, and at sorcery speed, too.
Go for the Throat - good in general, but really sub-par against Affinity. Might want to choose Smother over it.
Hero's Downfall - Dismember may be better here, unless you're with a group that sees a lot of Planeswalkers

Instead of running quad bolt, quad helix, triple electrolyze,and triple path you can run more Supreme Verdicts or Wraths of God, or if you're not in the mood for sweepers, run Wall of Omens and Restoration Angel. You just have a whole lot of spot removal. A lot of it might end up dead in your hand.

Chromatic Lantern? You seriously need better mana fixing.

Mass Extinction

Life and LImb + Sporemound = infinite mana, infinite creatures

If you're gonna play a five-color commander deck, you should play a more powerful commander. As it is, a 7/7 for 5 mana is good, but doesn't really do anything. Even Sliver Hivelord is better (in my opinion), because it dodges the numerous Wraths that plague the commander format, but personally I think Cromat or Progenitus would both be better options.

Too much spot removal. The idea should be to "kill" all the creatures before they even make it into play with Inquisition of Kozilek and Thoughtseize, then use Drown in Sorrow and Damnation to mop up against the few who do make it into play.

Oh, I thought you were gonna do some Infinite Reflection shenanigans. I know all about the legend rule; I thought you were gonna turn my guys into each other and kill my board.

Exalted Decks play like crap in Modern. Robots can trash them with little resistance, they have few answers to Melira Pod, outclassed by Jund, and shut down by control. So many fine casual decks are garbage in Modern.

Rafiq is only like 9 bucks. Rafiq into Finest Hour is just dastardly - it's like quadruple strike!

Ugh, that would be bad. But the only real answer is Mirror Gallery, and that would do nothing so much of the time. I think I'll just willingly lose to copy decks.

Cavern of Souls isn't legendary, and even if it were, I don't know what creature type I'd name (Legend isn't a creature type any more) . . . and Dark Depths doesn't really win without Vampire Hexmage or Thespian's Stage. I just included Into the North because it's strictly better than Rampant Growth because it can grab Arctic Flats.

Because Mana Leak.

Void Snare = bad. Sorcery speed is just awful. Just play Boomerang. Or even Into the Roil. Just not a sorcery-speed bouncer.

Of course, no deck is unbeatable. This one, for instance, is beat by Skylasher. However, you don't count on your opponent having the odd cards that beats this deck, you just play it like it is and maybe have some sideboard cards available.

Oh, and by the way, because Arcane Laboratory is so important, you might want to consider Drift of Phantasms to search is up.

Hopefully this drops the price of the Zendikar fetches?

Tenza, Godo's Maul would be pretty spankin'
