Question

[Cutthroatfinch]

Can I put cards from the Izzet Golgari duel deck in a standard deck, since that came out after innistrad?

If you are asking if you take cards out of the duel deck to put them in a standard deck no

[Cutthroatfinch]

Awesome, thanks!

However, if the card is also in the current standard print then yes I believe they can be used.
