Here's why it's so powerful:
* High Level: It's a Level 12 Synchro monster, meaning it requires a lot of materials to summon.
* Powerful Effect: It can negate the effects of all other monsters on the field, and it can destroy any other cards on the field.
While there are other Synchro monsters with high attack points, Shooting Quasar Dragon's powerful effects make it the most formidable in terms of overall strength.
