The Delver deck type, which is currently dominating every pro tour since it's becoming in late 2011 has been held highly as one of the best decks to ever have been made. But is this true? Of course a turn two 3/2 with flying is amazing, but it's getting to that point which makes Delver an insufficient deck. If one can't rely on a Ponder to rig their next turn, they have an, at minimum, 1/3 chance of having their Delver flip, as the deck runs at least twenty instants and sorcerys in the sixty card deck. Having to rely on luck of the draw, as with Miracles, makes Magic a game less about skill, and more about luck. I have personalty built and tested three Delver decks, one being my own, the other being Gerry Thompsons “Meta breaker”, and finally the nineteen land Delver deck that won a pro tour a few weeks ago. With all of these decks I realized that if I didn't get set up with something within the first three to four turns, I was hosed hard. What good is a Delver against a 6/6 Titan? Or a Mana Leak against someone with ten or more land? Sure I can use a Snap Caster to re use my graveyard, but this in turn weakens the Rune Chanters Pike and causes me to miss plays in order to make sure my opponent cant make theirs. There are other color splashes of Delver, including red/blue which can stomp hard as long as it gets it's Bonfire of the Damned and Delvers out, which continues to show that it's a deck that needs luck, rather than skill.
With the introduction of Restoration Angel, one is now able to flash in and bounce a Snap Caster already in play to get a second effect off him, and for four mana, a ¾ flier with flash is good in itself. But in a deck that relies on a card that needs a chance effect to flip itself and is also reliant on a single mana color needing to splash into a second to even run Restoration Angel, it makes little sense besides being a saving grace for a Go for the Throat or Tragic Slip.
Going back to the whole “speed” issue, one will notice that if they don't get a nigh perfect hand, they won't stand a chance in the long run after their first few turns. If you cannot get at least one Delver out and flipped by turn two or three, you will be sitting still attempting to Gitaxian Probe, Thought Scour and Ponder yourself into any creature or other removal spell what so ever. There are times where you can hold off your opponent, yes, but that doesn't negate the other amount of time where you are doing absolutely nothing but milling and killing yourself, which makes the deck unreliable. Yes, the deck is known for it's extremely good opening hand draws, but as with every deck if you don't get a hand with at least a land and a Delver you are going to be sitting pretty for a while.
I'm currently personally sold on my Esper Sun Titan build for a multitude of reasons, but the main one being that it is able to hold back and stomp Delver. As long as I have three land, I can play Lingering Souls to block, Forbidden Alchemy to dump and pull, Lilliana to kill, Image's to copy, the list goes on. I will most likely, but not always, be able to hold out past the mana leak range and get out my Gideons, Titans, and Elesh Norn. Even if Delver manages to get itself into gear and get three flipped Delvers coming at me for nine, I always have a Day of Judgment handy to stop them in their tracks. Delver has too many answers being run, and it makes the deck almost meta unreliable. Even Wizard of the Coast have told that Delver decks have a 50/50 chance of winning because there are so many of them being played, and with that high amount comes decks such as mine which are meant to destroy Delver where it stands.
Maybe some day there will be a Delver deck that can beat past the luck of the draw that the deck relies on so heavily. But with the 2012 core set and Ponder rotating out within the next three months, that just seems highly unlikely. Without Ponder, the deck is almost nothing. There's no way to cheat the draw, as Ponder is the only way to get past the 1/3 chance that Delver needs to function. But this is just me ranting, what do I know?
