Forum:Reveal Timing on Pot of Duality

I revealed the top three cards of my deck using Pot of Duality and added one to my hand. My friend said he didn't see what card I added to my hand and so I then had to reveal that card a second time. His specific claim was that whenever a card says something along the lines of 'add 1 ... to your hand', that somewhere in the rulebook it says that card must always be announced or revealed a second time. Would I have had to show him my card? Mind you, I did not do any quick-reveal nonsense. He had plenty of time to see the cards when I first revealed them. –PatPeter 18:03, January 4, 2012 (UTC)
