Planeshift is a small set with 55 commons, 44 uncommons, and 44 rares. These numbers are normal for a small set of this era. Foil cards are included in booster packs with advertised odds of 1 : 100 cards. The set was printed in Belgium. The existence of USA-printed Planeshift is unknown. [1]
Planeshift was sold in 15 card booster packs. Booster boxes have 36 packs.
The Planeshift printing uses striped collation with 10 × 11 sheets and 12 × 11 sheets. Packs are back-facing and contain 3 uncommons, 1 rare, and 11 commons (in that order). Foil cards are inserted only between stripes (in other words, after a card on the left side of the sheet before moving all the way back to the right), displacing a card of the same rarity.
3 Uncommons | 1 Rare | 11 Commons |
There is a single 10 × 11 common sheet that contains each common card twice. It has been reconstructed by observing pack openings. The choice of top row here is a mostly arbitary guess.
There is a single 12 × 11 uncommon sheet that contains each uncommon card three times. It has been reconstructed by observing pack openings. The choice of top row here is a mostly arbitary guess.
[1] The "Compilation of Manufacture Information for MTG Products" thread on the Magic Librarities Forum lists US-printed Planeshift as uncertain. I also did not find any during my research.
