[[File:EmpoleonVBattleStyles40.jpg|thumb|200px|right|[[Empoleon V (Battle Styles 40)|Empoleon V]] has a Rule Box and references Rule Boxes in its text.]]
A '''Rule Box''' (Japanese: '''ルール''' ''Rule'') is a box featured on certain {{TCG|Pokémon}} cards that is labeled a "rule" and contains an addtional rule that applies to that Pokémon card.<ref>[https://www.pokemon.com/us/sword-shield-chilling-reign-banned-list-and-rule-changes-announcement/ Pokemon.com Chilling Reign Banned List and Rule Changes Announcment]</ref> The term and its mechanical relevance were introduced in {{TCG|Battle Styles}}, but Rule Boxes first appear on {{TCG|Pokémon-EX}} in {{TCG|Next Destinies}}.

A Rule Box indicates a special property of the Pokémon. These are not {{TCG|effect}}s.<ref>[https://compendium.pokegym.net/ruling/1483/ Compendium ruling], Compendium VMAX, [[Team Compendium]]</ref> Rule Boxes can be loosely grouped into one of four categories:
*Most Rule Boxes increase the number of {{TCG|Prize card}}s the opponent takes when the Pokémon is [[Fainting|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}} (Prism Star) rule''' is one such case, only allowing a player to have one copy of a {{TCG|Prism Star}} 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 {{TCG|Radiant Pokémon}} 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 {{TCG|Mega Evolution Pokémon}} or a {{TCG|Primal Reversion Pokémon}} [[evolve]] from another Pokémon. 
*The '''BREAK Evolution rule''' is what allows {{TCG|Pokémon BREAK}} to have the {{TCG|attack}}s, {{TCG|Ability|Abilities}}, {{TCG|Weakness}}, {{TCG|Resistance}}, and {{TCG|Retreat cost}} of their previous evolution. 

Effects care about if certain Pokémon have Rule Boxes. Usually they exclude Pokémon with Rule Boxes from positive effects and include Pokémon with Rule Boxes in negative effects. Exclusion examples include [[Pot Helmet (Brilliant Stars 146)|Pot Helmet]], which reduces the damage a Pokémon that it is attached to takes from {{TCG|attack}}s by 30 as long as the Pokémon does not have a Rule Box, and [[Gloria (Brilliant Stars 141)|Gloria]], which searches the deck for three {{TCG|Basic Pokémon}} without Rule Boxes and puts them onto the [[Bench]]. An example of inclusion is [[Path to the Peak (Chilling Reign 148)|Path to the Peak]] removing the {{TCG|Ability|Abilities}} of Pokémon with Rule Boxes. This pattern does not always hold true. For example, [[Empoleon V (Battle Styles 40)|Empoleon V]] also removes Abilities from Pokémon, but only from Basic Pokémon without a Rule Box. In some cases, use of the term Rule Box replaces templating that used to name specfic mechanics. For instance, the older card [[Brigette (BREAKthrough 134)|Brigette]] has a similar effect to Gloria except that excludes {{TCG|Pokémon-EX}} from its triple search option and instead has a second option that searches for a single Pokémon-EX.

==Position==
[[File:LatiasCelestialStorm107.jpg|thumb|200px|left|With the {{Prism Star}} (Prism Star) rule, there's no space for [[Latias ♢ (Celestial Storm 107)|Latias]] {{Prism Star}} to have [[Pokédex]] information, so it doesn't.]]
On most cards that have a Rule Box, the Rule Box is positioned in one of two places: 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 [[List of Pokémon by National Pokédex number|number]], [[Pokémon category|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 {{TCG|Full Art card}}. These practices take up the Pokédex information space.) This has gameplay ramifications because some cards refer to a card's given height. Such cards cannot be used with cards that do not have a listed height due to a Rule Box.

==Exclusion==
[[File:NidoqueenPrimalClash69.jpg|thumb|200px|left|[[Nidoqueen (Primal Clash 69)|Nidoqueen]] has a {{TCG|Ancient Trait}}, but Ancient Traits are not labelled "rule" so it is not a Rule Box. It also doesn't have Pokédex information, but because of the artwork instead of due to a Rule Box.]]
[[File:CleffaNeoGenesis20.jpg|thumb|200px|right|[[Cleffa (Neo Genesis 20)|Cleffa]] has what is officially known as the "Baby Pokémon rule", but it is not templated as a box labelled "rule", so it is not a Rule Box.]]
There are other cases where Pokémon cards have additional rules on them that are separated from the main card text in a graphical manner. These are not Rule Boxes.<ref>[Kyle Sucevich on Twitter]</ref> For example, {{TCG|Ancient Trait}}s and the "How to play a Pokémon V-UNION" section on {{TCG|Pokémon V-UNION}} are not Rule Boxes. As a result, no cards released before {{TCG|Black & White}} have Rule Boxes.<ref>[https://compendium.pokegym.net/ruling/1508/ [[Team Compendium|Compendium]] ruling on Emperor's Eyes]</ref>

==Non-Pokémon cards==
[[File:PotionScarletViolet188.jpg|thumb|200px|left|[[Potion (Base Set 94)|Potion]] and other {{TCG|Trainer card}}s are described as having a Trainer Rule specifying how their subtype functions in their lower right corner, but this isn't a Rule Box.]]
[[File:LusamineLostThunder182.jpg|thumb|200px|right|[[Lusamine ♢ (Lost Thunder 182)|Lusamine]] {{Prism Star}} has the {{Prism Star}} (Prism Star) rule, but every card thus far only considers "Pokémon with a Rule Box".]]
While {{TCG|Prism Star}} {{TCG|Trainer card}}s and {{TCG|Energy card}}s have the Prism Star rule printed on them, only Pokémon cards have ever been described as having Rule Boxes. In fact, the rules provided for the {{TCG|Gym Leader Challenge format}} by the ''Alternative Play Handbook'' only mention Pokémon cards as not being allowed for use in the format due to having a Rule Box, with no equivalent sentence for Trainer cards and Energy cards. 
{{-}}

==Gym Leader Challenge legality==
The rules for the {{TCG|Gym Leader Challenge format}}, an unofficial format created by community members, exclude cards with Rule Boxes from the format. In some ways, the definition of what is and is not a Rule Box is different regarding this format compared to the official rules. 
*Prism Star Trainer and Energy cards are considered to have a Rule Box for the purposes of card legality, despite not normally being grouped as having a Rule Box.
*Pokémon with Ancient Traits were not allowed in the {{TCG|Gym Leader Challenge format}} until November 16, 2021.

==Cards with Rule Boxes==
<!-- This list does not nest subgroups of mechanics because TAG TEAM Pokemon GX do not have the Pokemon GX rule despite being a subgroup of GX. and V subgroups have rules separate from the V rule. It doesn't work. !-->
