4. Resolve the copy of Demonic Gifts, giving Dualcaster mage +2/+0 causing Dualcaster Mage to return to the battlefield when it dies this turn.
5. Activate Viscera Seer by sacrificing Dualcaster Mage.
6. Dualcaster Mage triggers, returning itself to the battlefieldt.
7. Repeat from step 3 an arbitrarily large number of times.
8. Resolve all Viscera Seer abilities, causing you to scry 1 an infinite number of times.
