Tour guide + Sangan

I have played against many who use the combo Tour Guide Of The Underworld with sangan.
Then i was wondering if Sangans effect is still activated when it is destroyed..

cause the Tour Guides effect says:
Its effects are negated, and it cannot be used as a Synchro Material Monster.

I would say no, when it says that the effect is negated.!
that means also if it is going to grave..

Tour Guide negates effects on the field, but Sangan's effect activate in the grave, so no it won't get negated & the player can search his deck.

Unless a card has a specific line of text tagged to it, if a card says it negates, it always applies purely to the field.
