Card Rulings:Macro Cosmos


 * You can activate "Macro Cosmos" even if you don't have "Helios - The Primordial Sun" in your hand or Deck.


 * You can only Special Summon "Helios - The Primordial Sun" when "Macro Cosmos" first resolves. It is not an effect that you can activate at any time or more than once.


 * If "Mystical Space Typhoon" is chained to "Macro Cosmos's" activation to destroy it, then you will not Special Summon "Helios - The Primordial Sun". Because "Macro Cosmos" is a Continuous Trap Card, it needs to remain on the field to resolve.


 * While "Macro Cosmos" is active on the field, monsters that are unaffected by the effects of Trap Cards (like "Elemental Hero Wildheart") are still removed from play instead of going to the Graveyard.


 * While "Macro Cosmos" is active on the field, if you Tribute a monster to Summon "Jinzo", the Tributed monster will still be removed from play.


 * You can activate "Polymerization" while "Macro Cosmos" is active on the field because sending Fusion Material Monsters to the Graveyard is an effect of "Polymerization" and not a cost.

Mentions in Other Rulings

 * D.D. Survivor: If "Macro Cosmos" is active on the field and a face-down "D.D. Survivor" on your side of the field is destroyed by battle, its effect will not activate. "D.D. Survivor" needs to be face-up when it is selected as an attack target in order for its effect to activate. (Similar to "Poison Draw Frog".)


 * Dark Lucius LV6: If "Dark Lucius LV6" destroys "Sangan" while "Macro Cosmos" or "Grave Protector" is active, the effect of "Sangan" cannot activate, so it is not negated. So you cannot Special Summon "Dark Lucius LV8".


 * Destruction of Destiny: If "Macro Cosmos" is on the field the 3 cards will be removed from play, but you will still take damage for any Spell or Trap Cards.


 * Dimensional Inversion: If your opponent controls "Macro Cosmos", "Banisher of the Light", etc., and an effect is activated by either player that sends a monster to the Graveyard, you can activate "Dimensional Inversion". This is because your monster is being removed from play (instead of being sent to the Graveyard) by the effect of your opponent's card.


 * Dimensional Inversion: If both players control "Macro Cosmos", etc., and a monster is sent to the Graveyard, assume that the turn player's effect is the one that removes it from play. So in this case, the opponent can activate "Dimensional Inversion" but the turn player cannot.


 * Grand Convergence: If an effect that destroys "Macro Cosmos" or removes it from the field is chained to "Grand Convergence", the effects of "Grand Convergence" will still resolve because the activation conditions were correct when it was activated.


 * Herald of Green Light & Herald of Purple Light: If "Banisher of the Radiance" or "Macro Cosmos" is face-up on the field, you cannot activate "Herald of Green Light's"/"Herald of Purple Light's" effect because you cannot send it and another Fairy-Type monster to the Graveyard for the cost.


 * Miracle Jurassic Egg: If "Macro Cosmos" or "Dimensional Fissure" is face-up on the field when "Miracle Jurassic Egg" is destroyed, it will still be removed from play instead of going to the Graveyard.
