Khans of Tarkir economics of cracking packs versus buying Fetchland singles
{first paragraph} Now that the Fetchlands are in the Khans of Tarkir (KTK) block we know that KTK will be a "money" block like Zendikar: you can open packs for specific cards that are worth a lot of money and not care much for the rest of the set, and you can buy sealed product and set it aside hoping to sell it at a much higher value 5 to 6 years down the road.

Now that I have played the five enemy color scry lands a ton (the ones in Theros) I can say that my attitude has changed from slightly negative to surprisingly positive (not that anyone should care, its my opinion, though). Scrying can be very useful and sometimes offsets that the land enters tapped.

{first paragraph} The announcement of the Onslaught Fetchlands now in Modern and Standard is bigger news for Modern than it is for Standard.
