I'm a bit shocked that he didn't mention Ajani. In a GW deck he'd be more then capable of dropping on turn 2, ticking up to 5, and then proceeding to pump your army while soaking up damage otherwise ment for you. Yes, he may be somewhat ineffective against Delver strategies that are f!@#ing everywhere these days, but he costs those decks either the time to get rid of him, or the risk of him hitting ultimate.
But since my favorate formats are all limited, I'll talk about some things I noticed at the prereleases I was at (these comments really only only apply to sealed and draft, constructed formats have ways to deal with plenty of these issues that I won't really get into now). Firstly, I'm not all that impressed with Exalted. I played against a BW Exalted deck Day 1 Match 1 with my UB control deck and I found it seriously underwhelming, even when my opponent managed to stick the Angel. Since they only ever attack with a single creature it makes it easy to shut off their offense for an entire turn with a resilient chump blocker or a well timed removal spell. Heck, DOWNPOUR bought me enough time in that match to find answers to pretty much every efficient creature my opponent played. I find that Exalted works better when supporting another strategy, or only if you get you hands on a good ammount of Rings (more on those later).
One thing that I saw was that Blue seemed pretty over powered, at least from a limited prespective. I feel that it combines with every other color in a great way. Talrand has proven to be insane with the right cards to support him, turning every instant and sorcery into at least a 2-for-1. Toss in an Archaeomancer to reuse your spells and you have an effective way to pretty much lock out an opponent (I won a couple of games by recycling Murders this way). I'd also like to give a shout out to mill as an alternate victory condition, or at least a way to make Jace's Phantasm bigger faster. I't fun and gives you a way to break most stalemates. Also Fog Bank... no words, just Fog Bank...
Black is another favorate of mine. My personal favorate has to be old hand Vampire Nighthawk. This little guy is capable of stealing games from the jaws of defeat single handidly. There was one game where I came back from 1 life REPEATEDLY to win all thanks to him. Stick him with a Ring or two and watch as your opponent slowly begins to cry. The assortment of other removal spells, board sweepers, card advantage, deathtouchers, and just a dash of Exalted is enough to seal the deal and I am very much looking forward to trying out some more UB control builds in upcoming drafts.
Red is fun. There's not much else I can say about it. While I preffered it in previous core sets, it still has most everything that mkade it cool with quick effient creatures and copious ammounts of burn, and the return of Mogg Flunkies makes me giggle a bit. The reason I don't enjoy it as much this time around is that a lot of the cards just feel objectivly worse than previous incarnations. Searing Spear is obviously just a downgraded Incinerate, Volcanic Geyser a worse Fireball, and Firewing Phoenix a fatter and less nimble Chandra's Phoenix (I just need to get this out of my system but I LOVED CHANDRA'S PHOENIX!!!!!!! There were games where I could replay her for peanuts compared to Firewing and the Haste was always incredibly relevent. In constructed I was able to return 2-3 Phoenixs to to play every turn in some games. Try getting THAT kind of inevitablity using Firewing "Chicken")... okay I'm done with that tangent.
What can I say about Green that hasn't already been said? Yeah, Thragtusk is incredible and Rancor is a never ending stream of PAIN. I'd be lying if I said that I don't have a soft spot for the big knuckleheads in this color, but I'm just a bit burned out from hearing about it all the time. Limited wise I like Green. It's going to be very hard for me to not go into the color if I get passed a decent Rare or Uncommon. There are a great ammount very efficient creatures, some awesome interactions with Roaring Primadox, and what can only be described as a stupid ammount of card advantage (Elvish Visionary, Garruk's Packleader, Groundseal, Garruk himself... WTF?????). One thing that I want to point out here is the contiuation of a powerful theme that has hung around drafts since at least Innistrad and was even the inspiration for one of the most succesful decks of Pro Tour Avacyn Restored: Unblockable Hexproof creatures. Innistrad had Invisible Stalker, AR gave us the combination of Latch Seeker and Elgaud Shieldmate, and now we can get another potent mix by sticking Tricks of the trade onto a Primal Huntbeast. I think that this is probably the most ballenced this strategy has ever been, it doesn't have the abusive speed of the Stalker+Anything combination, but it's a bit more powerful and resilient then the Shieldmate combo. There are very few things that can stand in the way of this kind of clock, but the drawback of having to wait until turn 5 as well as enchantment removal helps make this itteration just a bit more "fair".
I said I'd cover the Ring cycle, so I will. They are wonderful. I saw many people leaving them in sideboards with the excuse of "I'm not in the right color", but that really doesn't apply. You might not get the gradual pump in an off-collor deck, but the other abilities granted are all incredibly relevent. Giving a deathtoucher Vigilence can be a great way to sneak in damage while keeping up a defense, and who doesn't love Hexproof, aside from your opponent. Other than the rings, the one artifact I really enjoyed using was Staff of Nin. While expensive, the ability to provide both incrimental burn as well as card advantage that can be played in ANY color combination is often too good to pass up.
Yeah, thems my thoughts. Was it worth the hour I spent writing it? Who knows.
