I'm excited after seeing the Zendikar spoilers, I was worried WoTC wouldn't feature the Eldrazi under the later part of the block. I'll definitely be getting back into M:TG.
I normally only pick up the dual decks with planeswalkers as the decks are normally made for new player accessibility rather than card value, so there's been some bad ones (Heroes Verses Monsters for Theros was particularly bad). But the new dual deck looks excellent, some really good commander cards, at a guess I would say reasonably valuable cards include Avenger of Zendikar (~£5), Stirring Wildwood (~£3, though it might go for a bit more as dual manlands are always popular in modern) and Primal Command (~£4), with Seer's Sundial and Scute Mob both being popular in Commander even though they're not worth much. And the Eldrazi decklist hasn't even been released yet, but you can bet they'll be worth a bit.
It's been revealed, if you go on the article and-
Wait a second...did they cut it out? What in hell? Bollocks. It was there when I first read it. I wonder why they cut it.
I also love how they made Eldrazi accessible. They aren't the too-expensive-to-play broken cards anymore, you can handle them better.
P.S. Oh and also, full-art lands confirmed in boosters and fat packs. Also, new cycle of fetch.
