Again this type of drop is offered with a set where almost all of the value is in Mythic Rares. According to mtg.dawnglare, playsets of the rares in this set is worth $224, and none of the uncommons or commons are worth $1 or more.
So it's a bad value from that perspective, even if you have uses for all of these cards, which nobody does. This should be about $150 cheaper before it's worth considering.
TwoLeggedMammalAccording to ChannelFireball, using their preorder cart, for a playset of Origins rares alone, is ~ $496.69.
Which source is the better indicator of value?
According to the latest mtg.dawnglare (7/16/2015; day before general release), Origins rares playset (for the 28 out of 57 rares in the release listed) prices out to $325.56.
So it's a bad value from that perspective, even if you have uses for all of these cards, which nobody does. This should be about $150 cheaper before it's worth considering.
