Forum:Gold and Silva effect...

can someone please tell me wich effect of gold and silva's is activated when my opponent discards it to the graveyard, does they get special summoned? or does it lett me destroy 2 of his cards for GOLD and your opponent selects 2 cards in their hand and returns them to the bottom of their Deck in any order for SILLVA's effect, or are they both activated at the same time when your opponent sends it to the graveyard.

thanks a lot for your help
