Rule Box (TCG)

A Rule Box (Japanese: ルール Rule) is a box featured on certain cards that is labeled a "rule" and contains an addtional rule that applies to that Pokémon card.Pokemon.com Chilling Reign Banned List and Rule Changes Announcment The term and its mechanical relevance were introduced in , but Rule Boxes first appear on in .
A Rule Box indicates a special property of the Pokémon and is not considered an .Compendium ruling, Compendium VMAX, Team Compendium Rule Boxes can be loosely grouped into one of four categories:
*Most Rule Boxes increase the number of s the opponent takes when the Pokémon is Knocked Out, as a trade-off for the higher power level of the card. Most of these make the opponent take two Prize cards rather than just one as normal, as seen with the Pokémon-EX rule, Pokémon-GX rule, V rule, VSTAR rule, and the Pokémon ex rule. Some of these increase the number of Prize cards taken to three, as with the TAG TEAM rule, the VMAX rule, and the V-UNION rule. 
*Other Rule Boxes instead restrict the number of the card that can be in the same deck. The (Prism Star) rule is one such case, only allowing a player to have one copy of a card in their deck and additionally sending the card to the Lost Zone if it would go to the discard pile. The Radiant Pokémon rule is slightly different, only allowing a player to put one in their deck in total. This makes every Radiant Pokémon mutually exclusive to each other. 
*The Mega Evolution rule and the Primal Reversion rule cause the turn to end when a or a evolve from another Pokémon. 
*The BREAK Evolution rule is what allows to have the s, , , , and of their previous evolution. 
Some effects interact with Pokémon that have or do not have Rule Boxes, such as Path to the Peak removing the Abilities of Pokémon with Rule Boxes.
==Position==
Most Rule Boxes are positioned either in the bottom right corner of the card where the Pokédex entry is normally located, or just below the art of the card where the Pokédex number, category, height, and weight are located. If a Rule Box takes up one of these spaces, the card will not have the Pokédex entry or Pokédex information that would go in that space. (Many cards exclude Pokédex information even if they do not have a Rule Box taking up that space, because the art is either popping out of the art box, extended over the area of the card, or because the card is a . These practices take up the Pokédex information space.) As such, these cards cannot be selected by a few effects that query a Pokémon's listed height.
==Exclusions==
Other additional rules on Pokémon cards that are separated from the main card text in a graphical manner are not considered Rule Boxes, such as s and the "How to play a Pokémon V-UNION" section on . No cards released before the Series have Rule Boxes as well.Compendium ruling on Emperor's Eyes
s are described as having a Trainer Rule specifying how their subtype functions in their lower right corner, but are not considered to have a Rule Box.
While s and s have the Prism Star rule printed on them, only Pokémon cards have so far been described as having Rule Boxes.
