A loose Cosmic Eclipse pack runs about $70 in our July 2026 price snapshot and carries roughly $20 of expected value — a -72% margin, and that's the good deal among this set's sealed products. The booster box sits near $3,870 at -82%, and the Elite Trainer Box is an astonishing -92%. Nobody buys Cosmic Eclipse sealed for the math anymore. They buy it because it's the last set of the Sun & Moon era, and closed eras trade on scarcity, not EV.
What Cosmic Eclipse is
Cosmic Eclipse released November 1, 2019 — the twelfth and final Sun & Moon expansion, and the era's largest, with a 236-card base list and a secret-rare section that pushes the full count past 270. It's the send-off for the TAG TEAM GX mechanic, and it went out loud: a deep bench of alternate-art TAG TEAMs and 21 gold secret rares stacked at the back of the set.
Timing did the rest. Three months later Sword & Shield reset the game, and within a year the 2020–21 boom vacuumed up whatever late-SM sealed product was still sitting on shelves. Print runs from 2019 were modest by what came after, the era closed, and Cosmic Eclipse quietly crossed the line from "modern set" to "vintage-adjacent" — the same trajectory Hidden Fates rode from the same year.
The chase: alt-art TAG TEAMs and a wall of gold
The headline card is the Charizard & Braixen-GX alternate art — the fireside-scene secret rare that became one of the defining Charizards of the TAG TEAM era and carries a several-hundred-dollar price tag raw. Around it, the money in this set concentrates in a handful of well-known chases:
- Charizard & Braixen-GX (alt art) — the clear number one, and the card doing most of the pack price's heavy lifting
- Reshiram & Zekrom-GX (alt art) — legendary-dragon duo, a strong second-tier chase
- Arceus & Dialga & Palkia-GX (alt art) — the three-Pokémon TAG TEAM oddity, long a fan favorite
- Solgaleo & Lunala-GX (alt art) — the era's mascots getting their send-off
- Venusaur & Snivy-GX (alt art) — the sleeper of the alt-art board
- The gold secrets — 21 of them, from golden trainers to golden energies, each individually rare
That last point matters more than it looks. Spreading the gold slot across 21 different cards means any specific gold is a brutal long shot, and most of the 21 aren't worth much individually. The alt arts are where the value lives. For the current per-card board, run the live numbers for this set — the Worth the Rip calculator prices every card in the set from the same snapshot.
Pull rates: one hit slot, long odds
No official odds exist for Sun & Moon packs; the calculator uses community estimates, and you should read them as approximations. The model for Cosmic Eclipse's hit slot:
- Full Art Ultra: ~6.5% of packs
- Rainbow Rare: ~2%
- Gold Secret: ~1%
- Ordinary holo baseline: ~90.5%
A separate rare slot lands a GX about 11% of the time, and every pack has a reverse holo. Run the gold number out: at ~1% per pack, a 36-pack booster box produces about one gold secret every three boxes — call it $11,000 in boxes per expected gold, which then has roughly a 1-in-21 chance of being the one you wanted. The alt arts live inside the Full Art Ultra and secret tiers, so the same cold arithmetic applies. If the mechanics of hit slots are new to you, how pull rates actually work walks through the whole model.
Sealed products: pick your poison
Our July 2026 snapshot prices three products, and none of them flatter the buyer:
| Product | Price | Packs | EV | Margin |
|---|---|---|---|---|
| Booster Pack | $70.19 | 1 | ~$19.80 | -72% |
| Elite Trainer Box | $1,883 | 8 | ~$159 | -92% |
| Booster Box | $3,871.51 | 36 | ~$714 | -82% |
The ETB is the trap. Eight packs of cards for $1,883 works out to about $235 per pack — you're paying triple the loose-pack rate for a branded box and some sleeves, because ETBs from closed eras collect a display premium that has nothing to do with what's inside. The booster box is the "efficient" rip at -82%, which tells you everything about the category. One honest caveat: sealed markets this old are thin, and these prices move on a handful of sales. Treat the box and ETB figures as a wide band, not a quote.
Verdict: buy the singles, hold the sealed, rip nothing
Three lanes, same as every closed-era set:
- Want the Charizard & Braixen or any alt art? Buy the single. Known card, known condition, and you skip a ~$50-per-pack expected loss on the way there.
- Already holding sealed? Keep holding and store it properly. Cosmic Eclipse sealed is a scarcity asset now; ripping it converts a collectible into a -82% lottery ticket.
- Ripping for the experience? It's a genuinely fun set to open — deep hit list, era nostalgia — but price it honestly at roughly $50 of expected loss per pack. That's an expensive minute.
FAQ
Why are Cosmic Eclipse packs so expensive?
It's the finale of a closed era with 2019-scale print runs, an iconic Charizard chase, and no more supply coming. Demand matured after the printer stopped — the classic recipe for relic pricing.
What's the best card in Cosmic Eclipse?
The Charizard & Braixen-GX alternate art, by a wide margin. The other alt-art TAG TEAMs — Reshiram & Zekrom, Arceus & Dialga & Palkia, Solgaleo & Lunala — make up the next tier.
Is a Cosmic Eclipse booster box worth buying in 2026?
As a rip, no — about $714 of expected value for roughly $3,870, per our snapshot. As a long-term sealed hold it's a defensible vintage-adjacent position, but you're buying at collector prices in a thin market, so size the position accordingly.
