Rulings:

• 1/1/2011 If Prototype Portal has left the battlefield by the time its second ability resolves, you’ll still put a token onto the battlefield that’s a copy of the exiled card. On the other hand, if Prototype Portal is still on the battlefield at this time but there is no exiled card (because, perhaps, Riftsweeper’s ability caused the exiled card to be put into its owner’s library), no token is created.
• 1/1/2011 You don’t choose the value of <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" />. Rather, the value of X is defined by the activated ability.
• 1/1/2011 If the exiled card has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost (such as Chalice of the Void), that X is considered to be 0. The <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in Prototype Portal’s activation cost takes this into account, though it may be greater than 0 if the exiled card has other mana symbols in its mana cost (such as Riptide Replicator).
• 1/1/2011 You may not activate the second ability if no card has been exiled with Prototype Portal. In that case, the value of <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> is undefined and can’t be paid.
• 1/1/2011 Any enters-the-battlefield abilities of the exiled card will trigger when the token is put onto the battlefield. Any “as [this permanent] enters the battlefield” or “[this permanent] enters the battlefield with” abilities of the exiled card will also work.
