Duel Deck: Sorin vs Tibalt

The new Duel Deck 'Sorin vs Tibalt" comes out on March 15. It is s the 11th set in the Duel Decks series. I analysed 'Sorin vs Tibalt' decklists in terms of valuable cards. I spotted four cards out there and it is titled Sorin, Lord of Innistrad and Tibalt, the Fiend-Blooded plus Hellrider and Sulfuric Vortex. Therefore, in total approximately 35 event tickets and 117 other bulk cards used only by casual players. MSRP is $19.99, so it may look like very good deal, but do you think it really is? Don't ever consider buying such Duel Decks from WotC store online, if you want to provide every card available online in your bot, buy them from players, no matter how attractive may be purchasing directly from WotC. Sorin, Tibalt, Hellrider and Sulfuric Vortex price will start falling soon and will establish on 20 event tickets level. It won't happen the very next day, but soon.  It is good time to reduce the number of your Sorin, Lord of Innistrad and Hellrider cards. Remember, the most of players choose the cheapest possible option and usually cards from Duel Deck are slightly more expensive than theirs normal equivalents.  As a result these cards won't generate you much profits. What is your experience in trading Duel Decks or any other collectible stuff? Do you (dis)agree with my point of view?
