Dark Spell Regeneration — Ruling

Effetto 1

This card's effect that Sets a Spell Card from your opponent's Graveyard to your field is the effect applied when this card's activation resolves. (It targets 1 Spell Card in your opponent's Graveyard.)

This card's effect that Special Summons The Winged Dragon of Ra from your Graveyard is an effect that activates in the Graveyard. (It does not target. It can be activated optionally during either player's turn, but cannot be activated during the Damage Step. Banishing this card from your Graveyard and sending 1 Monster Reborn from your hand or face-down from your field to the Graveyard is the cost to activate this effect.)
Special Summoning The Winged Dragon of Ra from your Graveyard and sending 1 monster on your opponent's field to the Graveyard do not happen simultaneously.
Sending the Special Summoned monster to the Graveyard during the End Phase does not start a Chain.
