I hate to think this, but are Innistrad Dual Lands so expensive simply because they’re the best rares in the set? Sure, they are the first enemy dual lands printed since the original shock lands, but seriously, you’re looking at $25 a playset right now. I think they’re going to go down, but it’s making it hard for a lot of players to stay competitive in what’s become a very, very awkward format (that is, if you’re not playing Red Deck Wins).
I hate this Standard format. Please, Dark Ascension (the next set), save us!
