Palworld TCG Rarities and Parallels
Dawn of Palpagos uses a base rarity ladder plus a set of parallel treatments. The counts below come from Bushiroad’s own English card list.
The base rarities
The booster set contains 100 base card types: 34 commons (C), 30 uncommons (U), 24 rares (R), 11 double rares (RR) and exactly 1 card at SSS, which is the chase card of the set.
Parallel cards
On top of those 100, the set carries 61 parallel versions, which are alternate treatments of cards that already exist at a base rarity. They break down as 30 SR, 15 OSR, 12 SP and 4 SSP, plus one card that appears as both RR and SSP. That is 162 entries in total for the booster set.
Trial deck exclusives
Each trial deck holds 39 entries: 25 at TD rarity, 12 at TSR and 2 at TSP. Bushiroad expands these two as Trial Deck Super Rare and Trial Deck Super Parallel, and every trial deck guarantees one of them in place of a main-deck card. There are also promotional PR cards distributed outside the sets.
What the other letters mean
Bushiroad has not published an expansion key for SSS, SSP, SP or OSR anywhere official, so we are not going to guess at one. What is verifiable is where each sits in the ladder and how many exist, which is what the counts above show.
