Here's how monster levels function in Yu-Gi-Oh:
* Level: A monster's level is a fixed value printed on the card. It determines the monster's summoning requirements and can affect its attack and defense.
* Rank: Some monsters have a rank instead of a level. Ranks are used for Xyz Monsters.
* Level Up Effects: There are some monster cards or effects that can temporarily boost a monster's level, but this is only for the duration of that effect.
What you *can* do to make your monsters stronger:
* Summon Stronger Monsters: Summon higher level monsters that have stronger stats and abilities.
* Use Equip Cards: Attach cards like "Mystical Space Typhoon" or "Iron Chain" to enhance your monster's power.
* Activate Monster Effects: Many monsters have effects that can increase their attack, defense, or grant them special abilities.
* Tribute Monsters: Certain monsters require you to send other monsters from your field to the graveyard to summon them. This can be a way to get stronger monsters onto the field.
* Fusion, Synchro, Xyz, and Link Summoning: These advanced summoning methods allow you to combine monsters to summon powerful monsters with different abilities.
