Here's why:
* Game Mechanics: Yu-Gi-Oh! is a game of finite resources. Attack power is determined by the monster's base attack stat, which can be modified by effects, but always remains a finite number.
* Card Design: While some monsters have effects that can potentially create very high attack values, these effects are often limited by factors like:
* Conditions: They may only activate under specific conditions (e.g., the opponent controls a certain type of monster).
* Resources: They may require the player to spend resources like cards or life points.
* Limitations: The effects may have limitations on the amount of increase or the duration of the effect.
Examples of High Attack Monsters:
* "Blue-Eyes Ultimate Dragon": This monster's attack power is significantly boosted but is still a finite number.
* "Chaos Emperor Dragon - Envoy of the End": Its attack power can increase drastically depending on the number of monsters it destroys.
* "Number 39: Utopia": This monster can gain attack power through its effects but it is not infinite.
Conclusion:
While Yu-Gi-Oh! boasts a wide range of monsters with powerful effects, none possess the ability to have infinite attack. The game mechanics ensure that attacks remain within a defined and manageable range.
