Normal Monsters (Japanese:
Only Monster Cards with "yellow" backgrounds are Normal Monsters. There are Tuner and Pendulum Normal Monsters, such as "Tune Warrior" and "Flash Knight". Non-Effect Fusion, Ritual, Synchro and Xyz Monsters are not Normal Monsters. Some non-Normal Monsters can be treated as Normal Monsters with card effects, most notably Gemini monsters and some Trap Monsters.
The card text (or flavor text) on Normal Monsters is for illustrative purposes only, and has no effect on gameplay (except "Summoned Skull" and "Beast of Talwar", which have an archetype condition that includes them in the "Archfiend" archetype). These texts provide lore on how the monster related to other cards in the game, such as the flavor text of "Opticlops" which explicitly states that it serves "Dark Ruler Ha Des".
Though they do not have inherent effects, there are often Spell, Trap, or Monster effects associated with specific Normal Monsters. For example, "Dark Magic Attack" can only be used with "Dark Magician", "Huge Revolution" can only be activated with 3 specific Normal Monsters on the field, and "X-Head Cannon", "V-Tiger Jet" and "Dark Blade" are the specific targets for three specific Union monsters.
Normal Monsters have received some very powerful support cards for general use, such as "Birthright", "Summoner's Art", "Knight of the Red Lotus", "Princess Cologne", "Terratiger" and "Ventdra, the Empowered Warrior", "White Tiger" and "Blue Dragon Summoner", "Dark Factory of Mass Production", and "Creepy Coney". The Normal Pendulum Monsters "Dragon Horn Hunter" and "Lancephorhynchus" support Normal Monsters. "Thunder End Dragon" has a powerful effect, but requires 2 Normal Monsters in order to be Xyz Summoned.
"Rescue Rabbit" can Special Summon 2 Level 4 or lower Normal Monsters from the Deck, providing quick access to Xyz Monsters; this effect is so useful that Dino Rabbit Decks are built entirely around it.
Some Normal Monster support focuses on low-Level Normal Monsters (typically Level 3 or lower). There are cards that allow the Special Summon of large numbers of low-Level Normal Monsters from the Deck (such as "Human-Wave Tactics" and "Enchanting Fitting Room"), to then be powered up with cards like "Triangle Power", "Amulet of Ambition", and "Sword of the Soul-Eater", or used to get rid of the opponent's cards with "The Law of the Normal".
- Normal Monsters were the most common monsters when the Duel Monsters card game was introduced in the manga and released in the OCG and TCG, but as the game's strategies evolved, Effect Monsters became more common and fewer Normal Monsters were released or reprinted. Now, very few Booster Packs contain Normal Monsters, and even those that do contain very few.
