[Re: Macro Cosmos] 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. [Re: Macro Cosmos] 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. Passcode: 54493213 Set: Structure Deck: The Dark Emperor ATK/DEF: ?/?
