Changes

The '''Sphere Field Cannon''' is a machine created by Dr. Faker to destroy the [[Astral World]], located below [[Heartland Tower]]. After the finals of the [[World Duel Carnival]] ended, the Sphere Field moved to the cannon, destroying Heartland Tower in the process. A slot within it allows for Hart to integrate with it, with his powers being used with the "[[Numbers]]" to power it, using Astral and Yuma as bullets to completely destroy the Astral World. It can launch trash directly into the Astral World via a portal.<ref name="ep68">{{episode|Yu-Gi-Oh! ZEXAL|68|ref}}</ref> After the conclusion of the Duel between Yuma, [[Reginald Kastle|Shark]] and [[Kite Tenjo|Kite]] against Faker, the cannon was destroyed when the room collapsed. This is similar to a tractor beam which could fire and take over the world.<ref name="ep71">{{episode|Yu-Gi-Oh! ZEXAL|71|ref}}</ref>
