Mamaragan: The Card Behind One Piece's Biggest Search Spike

Mamaragan OP15-078 costs $20.00. It also draws more search traffic than almost any other One Piece card, including cards worth four figures.

That gap is the interesting part. People aren't looking it up because it's valuable. They're looking it up because they need it.

This guide covers what the card does, why it's searched so heavily, and what each printing costs. Card effects come from Limitless TCG. Prices come from PriceCharting's aggregated sold data, pulled 6 October 2026.

What Mamaragan actually does

Mamaragan is an Event card from OP-15 Adventure on Kami's Island. It has two modes, which is the key to understanding it.

Main phase: DON!! −2. Draw 1 card. Then rest up to 1 of your opponent's Characters with 5000 power or less.

Counter: Up to 1 of your Leader or Character cards gains +1000 power during this battle. Then, if you have 6 or less DON!! cards on your field, draw 1 card.

Read what that means in practice. In your main phase it's removal-adjacent disruption plus a card. On your opponent's turn it's a combat trick plus a card.

Both modes draw. That's unusual and it's why the card gets played.

Why a $20 card gets searched more than a $8,000 one

An Event card that replaces itself is never a dead draw. You play it for value in your own turn or hold it as a counter, and either way you get a card back.

That makes it a four-of in decks that can run it, which means every player building that deck looks it up, checks the ruling on the DON!! condition, and goes shopping for a playset.

Compare that to a manga art Luffy at $8,405. Very few people buy one, and nobody needs to check how it works.

Search volume on trading cards measures need, not value. A cheap card every competitive player must own generates far more lookups than an expensive card almost nobody buys. Mamaragan is the clearest example of that in One Piece.

Every Mamaragan printing and price

There are only four, which is unusual for a heavily played card.

Values move with the market. No graded comps are recorded for any printing.

A playset of four English base copies runs about $80. In Japanese it's about $37.

The language gap is unusually wide

Look at the alternate arts. English $47.69 against Japanese $10.17, a 4.7x difference for the same artwork.

Most One Piece cards show a narrower gap, and some run the other way with Japanese ahead. A 4.7x spread on a playable card usually means English supply is tighter relative to demand.

If you're buying to play rather than collect, the Japanese alternate art at $10.17 is the obvious value. Check your local event rules first, since language legality varies by region and organiser.

The absence of graded copies tells you something

Not one Mamaragan printing has a recorded PSA 10 sale.

For a card with this much search attention, that's a strong signal. It confirms the audience is players rather than collectors, because collectors grade and players sleeve.

It also means grading one is speculative in the most literal sense. There's no established graded market to sell into, so you'd be creating the first data point rather than entering an existing one.

On a $20 card, that isn't a bet worth making.

Where the card comes from

Mamaragan appears in OP-15 Adventure on Kami's Island, released 3 April 2026.

The name refers to Enel's thunder attack from the Skypiea arc, which fits the set's Kami's Island theme. Enel himself has an Alternate Art Manga card from the same set, OP15-118, trading around $777.96. You can compare it against other sets like Emperors in the New World and Carrying on His Will.

That's the pattern worth noticing. The set's collectible value sits in the manga art card, while its search attention sits in a $20 Event card. Both come from the same product.

Should you buy it?

If you play a deck that runs it: yes, buy a playset. At $20 per English copy or $9.31 in Japanese, it's a standard cost of building a competitive list.

If you collect: the English alternate art at $47.69 is the only version with collector appeal, and even that is modest.

If you're buying as an investment: no. Playable cards from in-print sets are the most reprint-exposed category in any card game, and Mamaragan has no graded market to support a price floor.

For reference on what does carry value in One Piece, the manga art tier is where the money sits, with cards like Luffy's OP05-119 at $8,405 raw.

How JK Index helps

We index the full One Piece catalog with sold history for every printing, including cheap playable cards that most price sites skip in favour of chase cards.

That's the useful part for a card like this. Knowing a Mamaragan playset costs $80 in English or $37 in Japanese is what actually affects your decision, and it's the kind of figure chase-card coverage ignores. You can track what you own in your portfolio or check current listings on the marketplace.

The takeaway

Mamaragan is a $20 Event card that draws search traffic rivalling cards worth hundreds of times more, because it draws a card in both of its two modes and competitive decks run four copies.

It has four printings, no recorded graded sales, and a 4.7x English-to-Japanese gap on its alternate art. It's a card to buy for a deck, not for a binder.

FAQ

What does Mamaragan do in One Piece?

The English base OP15-078 trades around $20.00 and the English alternate art around $47.69. Japanese versions are far cheaper at $9.31 and $10.17 respectively.
