Character info
The character
This card depicts the Legendary Marine Trench, a Stadium location in the Pokémon Trading Card Game rather than a character. It represents a deep, turbulent oceanic chasm associated with legendary Pokémon. It functions as a battlefield-altering location card rather than a creature with its own narrative.
This card
This is card 072/076 from the Storm Emeralda set (set code M6), printed in Japanese as an Uncommon Trainer-Stadium card. It is listed as the right side, card 2 of 2, of a combined artwork pairing. The illustration shows a dramatic seascape of jagged rock spires cutting through churning blue water, with seabirds and marine mammals in flight and motion, illustrated by danciao.
How it plays
As a Stadium card, it can be played once per turn beside the active Pokémon area, and it states that if another Stadium card is played, this card is discarded, with no duplicate-named Stadium allowed in play. Its printed effect doubles the HP recovered when all of your Pokémon heal HP from each other. The card also notes that it is not played as a single Trainer card alone, but combined with another card type chosen from two kinds in hand, entering play together as one Stadium card.

Authenticity
WinnTCG authenticated this card in hand, on the bench, against genuine Pokémon cards. It was checked four ways: light shone through it to check the core, its weight on a scale, its thickness measured, and its print pattern and surface texture under magnification.
