Changes

* Inflicting [[Inflict]]ing 300 [[Effect damage |damage]] and destroying all monsters on the [[Playing Field|field ]] are both resolved [[resolve]]d at the same time.

* If the 300 [[effect Damage|damage ]] would be reduced to 0 by the effect of “Des Wombat” "[[Des Wombat]]" or “Pikeru’s "[[Pikeru's Circle of Enchantment”Enchantment]]", “Grand Convergence” "[[Grand Convergence]]" can still be activated [[activate]]d and all monsters on the [[Playing Field|field ]] will still be destroyed.

* If an effect that destroys “Macro Cosmos” [[destroy]]s "[[Macro Cosmos]]" or removes it from the [[Playing Field|field ]] is chained [[chain]]ed to “Grand Convergence”"[[Grand Convergence]]", the effects of “Grand Convergence” "[[Grand Convergence]]" will still [[resolve ]] because the [[activate|activation ]] conditions were correct when it was activated[[activate]]d.

* “Barrel "[[Barrel Behind the Door” Door]]" can be chained [[chain]]ed to this card.

* If there is a monster on the [[Playing Field|field]], you can [[chain “My ]] "[[My Body as a Shield” Shield]]" to this card.
