Umbreon & Darkrai GX Base (Pokemon Japanese Tag Team Starter Set #010/031) has a PSA 10 market cap of $1.04M on CardZ Marketcap as of Oct 13, 2026: PSA 10 price $209 × PSA 10 population 4,978. Ranked #663 by market cap among 1,677 ranked cards across CardZ Marketcap.

Background

010/031 is the Japanese starter-set Umbreon & Darkrai GX from the May 30, 2019 TAG TEAM GX box. Mitsuhiro Arita drew this regular print. It was one of two fixed-list Tag Team pairs in those starters, beside Espeon & Deoxys GX.

Dark Moon GX can shut off Trainer cards and threaten a knockout with enough Energy. A later special full art by so-taro showed up as English SM241 in the TAG TEAM Powers Collection; that is a different finish.

The desk still files it as the starter exclusive first, then as a slabbed common of the early Tag Team wave.

METHOD & DATA

How the market cap number is built

Market cap is the current PSA 10 reference price multiplied by the verified PSA 10 population, recalculated on every daily update.

Reference price: The most recent completed PSA 10 sale captured inside CardZ Marketcap tracked coverage. Lots are unitised down to a single card, and a sale priced far outside its own recent range is rejected in favour of the next most recent one.
Population: The verified PSA 10 population for that exact printing — language, set, collector number and parallel are never merged across printings.
Gaps: A card with insufficient data coverage in the window is marked as accumulating rather than being given a filled-in number. A missing value stays missing, never zero.
