Triggering from GY

[Grumozard]

"If this card is sent to the GY by an opponent card effect: You can X"

The point is no: This monster has been sent to the GY by Dakini's effect, can my opponent trigger the above effect?

[greg503]

Was it your Dakini's effect that sent it to the GY?

[King_Kai]

if its in your GY, youre the only person that can activate the effect, but since Daikini forces player action, your card is never considered as being sent by card effect, so wont trigger regardless.
