It's important to note that I only feel this way about Standard; for obvious reasons Eternal formats require a more liberal use of the "banhammer" to ensure their long term health and stability. Additionally I'm willing to accept that sometimes cards just slip through the cracks and end up impacting Standard in a way that design neither intended nor could have easily predicted; Mirrodin-era Artifact Lands, Disciple of the Vault and Skullclamp all come to mind here. In these cases we were talking about a legitimate, honest to God mistake that lead to the banning of a number of common and uncommon cards that literally everyone was happy to see go. Finally I should mention that while I was a little upset at the time I eventually came to understand the Jace/Stoneforge Mystic ban as a one time only effort to boost increasingly flagging tournament attendance with the understanding that both of these cards would only be legal for another 3-4 months in Standard anyway. In short; I am against banning cards in Standard but I'm willing to make an exception in the case of obvious mistakes or overt consumer reactions that directly affect tournament attendance numbers in a negative way. Unfortunately in this case I have an extremely hard time believing that any of these cards were a legitimate "mistake" and I near as I can tell tournament Magic is as or more popular than it's been in years. Just a few weeks ago I attended a 181 person PTQ that was so overcrowded the organizer was openly offering 12 packs to any player who dropped after rounds 1 or 2; clearly Delver is not keeping grinders away in droves the way Caw Blade did last summer.
this the response was overwhelmingly positive and only the stubborn or contrary had any question about how powerful this card was. It's also not as if this opinion was confined to beginners, whiners and "durdles" either folks; some of the best players in the world were openly singing the praises of this format defining monstrosity long before "Snappy" was even available for purchase. You may be tempted to pass all of this off as hyperbole or exaggeration but when some of the greatest minds in Magic (snicker) are absolutely salivating to get their hands on a card you can rest assured that it's the real deal folks. Finally, even if you were one of the few that doubted "Snappy's" power, it's hard to argue that the market as a whole wasn't very excited about Snapcaster Mage. I know for example that at the shop I personally manage we had to keep a waiting list of customers who wanted to buy both foil and regular Mages before the set was even released; I honestly can't remember having to do that with another unreleased card before or since.
"The first place I want to go with Snapcaster is a deck with Mana Leak and Ponder, since right away that’s some nice value."
Oddly enough this was also the very first place my playgroup and I went with Snapcaster Mage and frankly if these card interactions weren't the first place the various Playtest teams working on this went, I think WotC should probably hire a new team. The phrase "obvious card interaction is, um, obvious" comes to mind here and I pretty much refuse to believe nobody at the company read Snapcaster Mage before he went to print. It's literally that simple folks; there is no ambiguity whatsoever about this card and simply reading the text makes it pretty obvious that this card is designed to "re-buy" cheap instants and sorceries. In other words I believe that just by printing Snapcaster Mage the company was openly stating that they had no problem whatsoever with decks that featured up to 8 Mana Leaks/Ponders/Doom Blades/etc in the current Standard format. Was this arrogant? Yes. Was Snapcaster Mage an incredibly dangerous card to actually print? Yes. Were we as players supposed to realize this in advance and avoid buying the card because doubling the number of counters/cantrips/kill spells in your deck is ridiculously broken? I'm pretty sure that's a "no". Would Innistrad have sold nearly as well without Snapcaster Mage? I don't have a crystal ball folks but I would also have to assume that's a no; I know I kept drafting long after I'd lost interest in the format just trying to open more Snapcasters (and Trafts to be fair). Therefore, in light of what we know and what we can obviously infer from both WotC marketing efforts and the text of Snapcaster Mage itself, is it fair in any way, shape or form to say that Snapcaster Mage was somehow a mistake? I'm not asking if he's broken folks because I honestly already know he's broken; the question is can any reasonable argument be made to suggest that WotC didn't also know that Snappy was broken and just printed him anyways? Even if you could find such an argument wouldn't it be so convoluted and so fundamentally based on gross incompetence as to paint the company in an extremely poor light anyway?
So now let's close our eyes and imagine that somehow this ban does happen; we wake up Wednesday morning and find out that Snapcaster Mage will no longer be legal in Standard as of July 1st. How does this make you feel? Are you happy that an obviously overpowered and fundamentally dangerous card is now barred from Standard? Do you find yourself asking "what took so long?" Does it bother you that WotC used this card to hype up/sell millions of packs of Innistrad only to turn around and ban it 9 months later after you'd paid all your money and opened up all your packs? Would you regret the decision to buy or trade for Snapcasters as single cards? Would you feel used? Wouldn't it feel to you like the penalty for printing an obviously overpowered/dangerous card has been shifted towards you, the consumer when it really should be on whomever decided to print such a ridiculous card in the first place? Would you ask for a refund and if you did ask would you actually expect to get one? One last question folks; would your answers depend on how many Snapcasters you owned, what formats you played and how much you actually paid for the card in the first place?
Of course, we're only dealing in the realm of hypothetical questions here; I personally don't think WotC is incompetent and I doubt they actively think I'm stupid. I suspect that there are many people involved in the "making of Magic" who wish Snapcaster Mage hadn't been printed but ultimately I trust that they know that banning Snapcaster now would only punish the customer for this design "mistake". I also suspect that WotC keeps a careful eye on tournament attendance and therefore they know that if people really are upset about Delver being the best deck in Standard they certainly aren't saying so with their time and wallets. Finally I believe the people who make Magic are fine geeks; men and women of honor who understand that for the time being the only fair solution is to lie in the bed they've made for themselves until such a time as normal Standard rotations remove the "problem" as a whole.
In summation folks I would advise against holding your breath while waiting for a ban in Standard to solve the Delver "problem". Frankly I'm not even entirely sure there is a problem; something has to be "the best deck in Standard" and at least so far the dreaded Delver hordes aren't keeping people away from tournament Magic. If there is a ban however don't bet on it being against Snapcaster Mage even though he is obviously the most powerful card in Standard's best deck. To take such an action would force WotC to either admit gross negligence/incompetence or risk insulting my intelligence and somehow I doubt they're trying to do either.
