Forum:Pot of Duality and special summoning restriction

I'm kinda confused because of this cards last sentence: "You cannot Special Summon during the turn you activate this card". Someone claimed that this restriction is the "cost" of this card, so if it gets negated, the restriction still applies. Is that true?

Also, once I was told that you can special summon before activating this card. I'm pretty sure that's not how it works, but I would like to know if it is actually possible. - BronzeJohnson (talk • contribs) 19:33, December 1, 2013 (UTC)
