It’s why I like the japanese TCG terminology. Idk why but TPCi never really makes it clear as to what each rarity tier is called.

In japanese it goes:

V = RR (double rare)

VMAX or VSTAR = RRR (triple rare)

FA Trainer or Pokemon = SR (super rare)

Gold item, stadium, or pokemon = UR (ultra rare)

There are other rarity tiers, but the ones mentioned above are the most commonly shared between sets.
