A pre-Worldwake look back at post-Zendikar blue.
Blue was never bad. Just not as good as we’re accustomed to.
A 450-lb man who loses 150 lbs—a full 33% of his body weight—would certainly not be considered “skinny” by any means.
This, I feel, sums up the current state of blue in Standard. While blue may have been worse between October and January than it ever has been, in hindsight I think it was a mistake to say it was “bad.” Counterspells were narrow and card-drawing was much less effective, true, but the color still had its strengths.
To wit: There was a time when many considered Morphling to be the best creature ever printed. With a wealth of abilities previously unheard of, Morphling could pump itself to 5/1, stack damage, and then become a 1/5; it could gain Flying; it could gain Shroud. It could untap itself, doing a passable impression of Vigilance.
Now compare Morphling to Sphinx of Jwar Isle:

For 1 additional mana, the Sphinx enters the battlefield with Flying. It enters the battlefield with Shroud. It enters the battlefield as a 5/5, and for all of these Morphling-esque characteristics it requires no more mana than the inital investment. It trades faux-Vigilance for an ability that—in a format with fetchlands, cascades, and soon Treasure Hunts—may be even more relevant. (Not to mention “Knowledge is Power” is the unofficial mantra of the blue mage, right?)
Could the Sphinx actually be better than Morphling?! Well, yes and no. It’s all about context, and when Morphling ruled the skies, blue spells were at their best. (And as much as I would’ve loved to see it, if Morphling were to have been reprinted it would likely occupy the slot in your trade binder right next to Meddling Mage.)
Still, the Sphinx exemplifies the quintessential blue finisher quite nicely: difficult to block, and easy to protect.
No, blue was not bad. Rather, it simply could not stand on its own. Yet, with another color or two along for support, blue found a way to stay strong. With a bit of persistence, blue-based control strategies started showing up as early as six weeks into the post-Zendikar format! At Worlds (late November), a Standard RWU Control deck was in the Team Finals, and Gerry Thompson unveiled his “Spread ‘Em” deck. As Conley Woods put it:
Typically, control decks are only able to emerge as “good” decks once a metagame as been firmly established. This is because the deck needs to know exactly what problems exist in order to determine which answers it must run. (Blue Uprising)
The difference between pre-Zendikar blue decks and those we’ve seen of late, as Conley goes on to point out, is that usually the counterspells are more versatile. This allows them to appear a bit earlier, as their answers don’t have to be so specifically tailored for the metagame. It is this loss of versatility, coupled with the loss of Instant-speed library manipulation, that fueled the perception of blue’s demise.
So, now we have Worldwake. Now we have the Mind Sculptor himself to help sculpt our hands into the ideal mix of answers and threats. We can dig for Treasure in the Halimar Depths, and accelerate our mana by drinking from the motherlovin’ cup. BLUE IS BACK!!!1!!

Not so fast. Let’s take a step back.
Blue mages—like starving children in a frenzy over a hunk of stale bread—have managed to drive the price of Jace, the Mind Sculptor to near-Baneslayer levels. I’m not exactly saying the price is unwarranted, because the card is certainly a piece of beauty, and I hope it’s every bit as good as people are expecting. But it has yet to prove itself. Had JtMS been released while Lorwyn was Standard-legal, I’d have been surprised to see it reach a pre-sale price half as high as it’s seeing now.
But, but…we’re SO HUNGRY!!
Worldwake is certainly giving blue a nice shot in the arm, don’t get me wrong. But I think we’re putting the cart before the horse, here. Blue mages are feeling so under-nourished from Zendikar that what may turn out to be a Happy Meal is looking like Thanksgiving Dinner.
So yes, go test your blue-based control decks. Play your Jaces, and your Treasure Hunts (I know I will be). But don’t set your expectations so highly that anything less than “bah-ro-ken” is a disappointment. I don’t think Mono Blue Control will be a reality, but pair it with a pal and I think blue control decks will be just fine.
