Forum:~~Card Ruling Query: about dark world and dark deal~~

for example: my opponent use a spell card and i used dark deal and my hand has sillva, goldd and broww and after "randomly"(actually when its random, i let my opponent choose for me since he don't see my hand) discard either of the three, will: goldd/sillva be special summoned + secondary effect or secondary effect only occurs? and if broww was the one being discarded, will i draw 1(primary effect) or 2(secondary effect) please help since the rulings on broww is quite confusing(especially broww)
