Character info

The character

Slowbro is the Hermit Crab Pokemon, National Pokedex number 080, and the evolved form of Slowpoke. It gains its sharper mind and distinctive shape after a Shellder bites onto its tail. Despite the apparent improvement, Slowbro remains known in the games and anime for its sluggish, absent-minded demeanor.

This card

This is Slowbro, number 24 out of 108 in the Dark Explorers set, printed in 2012 with uncommon rarity. The artwork by Kouki Saitou depicts Slowbro walking alongside a Tyranitar-like companion on a grassy path near a wooden fence. The card uses the standard Stage 1 evolution layout with its Pokedex data strip beneath the illustration.

How it plays

This Water-type Stage 1 Pokemon has 100 HP and evolves from Slowpoke. Its Ability, Airhead, prevents it from attacking if its controller has 2, 4, or 6 Prize cards remaining. Its attack, Lazy Headbutt, costs one Water and one Colorless Energy, deals 80 damage, and puts this Pokemon to sleep. It has a weakness to Lightning (x2), no listed resistance, and a retreat cost of three Colorless Energy.

Card details confirmed

A card with this name and number exists in the public card catalogue, in Dark Explorers, a set of 108 cards, rarity U. The details on this certificate match it.

Illustrated by Kouki Saitou and published 2012-05-09. Both come from the public catalogue, not from WinnTCG.

A catalogue match is not the authenticity check. It confirms the card is the card it claims to be. Whether it is genuine was checked separately, on the card itself; see Authenticity below.

About this card

#80 in the National Pokédex · a Generation I Pokémon · 157 different cards of it exist · it evolves from Slowpoke.

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.

How this card was graded

WinnTCG graded this card in hand, on the bench. The card was in our hands, and we sealed the case ourselves. We photographed it here under controlled light to show which card is in the case and where anything we marked sits on it.

If you are buying this slab: the grade is WinnTCG’s judgement of the card that was in front of us, and WinnTCG sealed this case. The photographs above are of that card. Compare them against what you can see through the case, because a case can be opened by anyone who has held it since.

The working behind this grade

Every grade here is published with its reasoning. The report states what each measurement returned, what the model proposed on each axis, where the grader disagreed with it, and every defect marked on the photographs above.
