With Evelyn on the battlefield, cast Ghostly Flicker, then cast Dualcaster Mage
Copy Ghostly Flicker with Dualcaster Mage
With the copy, target Dualcaster Mage and Evelyn to blink them
When Evelyn comes into play, exile each opponent's top card
When Dualcaster Mage comes into play, copy Ghostly Flicker again
Repeat the process.
