Holofoil

Holofoil cards (also known as Holographic Foil, Foil, Holo, Reverse Holo, Reverse foil or Holographic) are a special type of card from the Pokémon Trading Card Game. Most are Pokémon cards. They are identical to their normal counterpart aside from a Holofoil effect in the picture (Holofoil) or the card background (Reverse Holofoil). A small amount of Rare () cards within each expansion are Holofoil. They may be pulled from Booster packs as the rare card, but is not guaranteed. They are rarer compared to non Holofoil rare cards.

As of the japanese Black & White collection expansion sets, a new form of rarity symbol was implemented, instead of utilizing shapes to symbolize rarity, it was replaced by letters, so replaces on Rare cards, which are all Holofoil.

As of the English Scarlet & Violet expansion set, all Rare cards are now Holofoil.

In most of the English versions of Japanese sets, cards that were originally only holofoil are given non-holofoil counterparts. The e-cards are an exception to this, as even the Japanese versions of the sets had holofoil and non-holofoil versions of cards. Only the non-holofoil versions had dot codes that could be read with the e-Reader. This was apparently because the holofoil caused complications with the dot codes. When holofoil cards have non-holofoil counterparts, the non-holofoil cards are the more common of the two, even though both are marked with the same rarity. As such, they are numbered differently within sets and generally considered different cards in terms of collectibility. In play, however, the cards operate the same, and thus are viewed mostly as the same.

Both crystal and pearl figures from the Pokémon Trading Figure Game appear to be based upon this concept. However, unlike the cards, the figures are not numbered differently.

Sheen

Sheen or Mirror Holofoil is used for all Holo cards from XY, and on various promotional cards. There are differences in the pattern depending on the language of the card; Japanese Holofoil cards refract light in a diagonal direction from bottom left to top right across the entire card; Korean Holofoil cards have the same effect and direction, but only cover the image of the Pokémon; and international releases have the same effect as Japanese cards, but only cover the image, and the direction is from bottom right to top left.

Reverse Holofoil

Reverse Holofoil cards are an alternative print of the cards in a set. Since Legendary Collection, one Reverse Holofoil card has been included in each booster pack. In contrast to a regular Holofoil card where the effect is applied to the picture, a Reverse Holofoil usually has the effect applied to the entire card apart from the picture, or the picture uses an alternative holo pattern, in addition to possible background patterns. A Reverse Holofoil counterpart is usually available for every card in a set, excluding Ultra Rare and Secret Rare cards, and any full-art cards.

1st Edition cards were last printed in Neo Destiny, and were ceased to be made at this point mainly due to 1st Edition prints regularly having delays, causing them to be received after the Unlimited print runs had arrived at retail. To replace these and to appeal to collectors, Legendary Collection was the first set to include Reverse Holographic cards. Wizards of the Coast used Magic: The Gathering as a basis and made a Reverse Holographic card for every single card in the set, with each booster pack containing one Reverse Holographic card, with only a few exceptions. This trend continued with all Wizards of the Coast expansions, and carried over with Nintendo's occupation of the TCG, appearing in all main expansions to the modern day.

The designs of Reverse Holographic cards have changed many times since their introduction, with many sets featuring unique designs.

Legendary Collection featured a "fireworks" design.
Expedition Base Set to EX Team Magma vs Team Aqua featured a plain holographic design.
- Both the Holofoil and non Holofoil rare cards had identical Reverse Holographic counterparts in Expedition Base Set (apart from the card number). Wizards of the Coast rectified this in Aquapolis and Skyridge by numbering the Holofoil cards differently (e.g., H12) and not producing Reverse Holofoils for these cards.
EX Hidden Legends swapped from the background of the card being holographic, to featuring an energy symbol holo pattern in the picture window with the type of the Pokémon shown as a faint foil symbol in the attack box.
EX FireRed & LeafGreen featured an energy symbol holo pattern in the picture window with a Poké Ball shape shown as a faint foil symbol in the attack box. Reverse Holo versions of the Rare Holo cards also have gold text for the Pokémon name and a holo rarity symbol to avoid confusion between these and the Reverse Holo versions of non holo cards, which continued until Diamond & Pearl.
EX Team Rocket Returns featured the same pattern as EX FireRed & LeafGreen, but with the addition of the set logo in the bottom right corner of the picture window.
EX Deoxys features a "wheel" holo pattern and the set logo in the bottom right of the picture window.
EX Emerald features a Poké Ball and stars holo pattern and the set logo in the bottom right of the picture window.
EX Unseen Forces features a similar pattern to EX Emerald, but with a 3D Poké Ball pattern instead and the usual set logo in the bottom right of the picture window.
EX Delta Species to EX Power Keepers feature the same foil used on the standard holofoils on the background image, with the main difference being the usual set logo in the bottom right of the picture window. The Reverse Holofoil versions of the regular Rare Holofoils and regular Rares also have a Holofoil HP text, in addition to the usual holo Pokémon name and rarity symbol. Reverse Holo versions of the Rare Holofoils also feature a holo card border.
Diamond & Pearl to Black & White return to featuring a plain holographic effect to the background of the card.
Emerging Powers to Steam Siege feature the card's respective Type symbol in the background of the card (Poké Balls for Trainer cards, and a variant of the Colorless symbol for Special Energy cards). Steam Siege's dual-type Pokémon cards use both types' designs on either side of the split in the background.
Plasma Storm, Plasma Freeze, and Plasma Blast again feature a plain holographic design for Team Plasma cards only.
Primal Clash, Roaring Skies, and Ancient Origins use the plain holographic design for Ancient Trait cards, but only on the area with the Pokémon's name and on the bottom quarter of the card, where the Weakness, Resistance, and Pokédex entry are.
Double Crisis uses the plain holographic design for all cards except Team Aqua's Kyogre and Team Magma's Groudon , which do not have Reverse Holofoil versions.
Evolutions returns to featuring the plain holographic design for all cards.
Sun & Moon to Cosmic Eclipse use an updated design similar to the one used from Emerging Powers to Steam Siege, but with a large version of the card's Type symbol (or Poké Ball) on the left side of the card.
Sword & Shield onwards use a "tile" design with the Type symbol or Poké Ball inside each "tile."
