On the 17th May, its average value on TCGplayer was $5.35 (3.98), while today it's worth $5.09 (3.79)
First up, I should tell you that Set Boosters are going to cost a little more than Draft Boosters (we estimate about $1 more per pack, but it may vary from region to region), but because you have the opportunity to open more rares per pack (you can open up to four rares or mythic rares in a Set Boosterboth wildcard slots, the rare slot and the foil slotand that's not even counting The List ), we expect that you will get the same number of rares and mythic rares per dollar spent as you would buying Draft Boosters
Spreading them into different baskets feels even better
Astrologian's Planisphere This two-cost Blue artifact Equipment with job select Equip for 2 will make it a Wizard and then as you cast non-dorks, toss a +1/+1 counter here and then on your third card drawn each turn, not just yours - brilliant win con there for Spellslinger brews and Commanders for Commander Damage in Cantrips
In my end step, sacrifice Sheoldred, Whispering One to bring Wurmcoil Engine or Burning-Rune Demon on the field
