-First, Normal Summon Star Seraph Scepter. Because you Summoned Scepter, you can trigger its search effect and activate Sovereignty’s Special Summon ability.

-Because both effects triggered at the same time, you decide what order they go on the Chain. Make Sovereignty’s effect Chain Link 1, and Scepter’s search Chain Link 2.

-When the Chain resolves, search another copy of Sovereignty from your Deck with Scepter. Then Special Summon your first copy of Sovereignty and draw a card for its effect.

-Since the Special Summon of a “Star Seraph” monster happened during the last Chain, you can now activate the Special Summon effect of the Sovereignty you searched with Scepter on a new Chain.

-Special Summon the second Sovereignty to draw a card.
