Can Swallow Flip be activated when Thunder King Rai-Oh attempts to negate a Special Summon?!
Thunder King Rai-Oh attempts to negate a Special Summon, and you want to use Swallow Flip.
No. Swallow Flip responds to effects that trigger on a successful Special Summon. Rai-Oh's effect is used before the Summon is successful, so it is not in response to a successful Special Summon and Swallow Flip cannot be used.
