I used to check my Magic card prices from the magazine, Inquest, but that magazine was discontinued from 2007. I stopped reading way before that once I quit Magic long ago. I found another source to check for Magic card price: tcgplayer.com store.
I was actually studying the Event Decks thinking of combining 2 to form a viable deck but then I found the above site which list out the card prices from various sources. You will be shock to find that most of the rare cards in the event deck barely make up the retail price of USD$25 set by Wizards of the Coast.
Hold the Line cost from rare-s: Approx $13
Deathfed cost from rare-s: Approx $11
Illusionary Might cost from rare-s: Approx $12
Vampire Onslaught cost from rare-s: Approx $18
Rot from Within cost from rare-s: Approx $17
War of Attrition cost from rare-s: Approx $17
Into the Breach cost from rare-s: Approx $6
Infect and Defile cost from rare-s: Approx $8
Granted you will also get uncommon and common cards which I did not factor in for the cost, the most expensive cards you can get from the event deck are Inkmoth Nexus($12-13) and Phantasmal Image($9-10). The uncommon and common cards aren't very expensive and if you order everything over the net, the decks are going to be cheaper and you can probably build a stronger deck as you get to pick cards. Buying 2 Event decks suddenly do not seem like such a good idea...
On another note, you will be able to checkout the upcoming Dark Ascension cards at the tcgplayer.com store. Looks like Wolf/Werewolf are going to get a lot of support.
