Rules text is not always constant, and some can differ slightly even for the same ability between different sets. For example, there is 「タップされていない」 (Not tapped) and 「アンタップされている」 (Has been tapped) to refer to untapped creatures. As a result, reprinted cards often have changed text.
As a general rule, if the text of the same card is changed for a reprint, the card should be treated to use the latest versions card text (see Errata). However, this is not true is the reprinted card has a misprint (such as Perfect Galaxy, Immortality Elemental being a spell instead of a creature, or having Silent Skill instead of Shield Force.)
Some card texts such as Chaos Fish or Chain Deathmatch can have complicated text to comprehend, so in order to prevent misunderstanding, players should fully understand the card before playing them in a game.
On occasion, some cards have illustrations or foil effects that may pop out of the frame making it difficult to read, reminder text explaining keyword abilities may be omitted due to the rarity of the card, or cards written in Forbidden Characters. To rectify this issue, other printed editions of the cards or the card list on the official websites could be checked.
Although the flavor text is written in the same area as the effect text is found, it has no effect on the game, and is usually just referred to as "flavor".
There is card text on most cards, but some creatures have none and are commonly called Vanilla.
Rockman EXE & Katta and Parlock ~Crossword~ have uniquely special card text, that varies based on different conditions being met. Please Marry Me!! also features 2 abilities in its text (including a keyword), but they have no effect on the game state. The text written on Great Thanks is written vertically, but it's not treated as an ability or flavor text.
