Shred the Stage!

When Shred the Stage enters the battlefield,
convert all non-believers.
During your upkeep, create two 1/1 colorless fan
token creatures. They gain haste until end of turn.
When Shred the Stage leaves the battlefield, you
may tap 6 colorless fan tokens and yell "Encore!".
If you do, return Shred the Stage to the battlefield
and create a 6/6 Queen of the Reich black, red and blue token creature with trample.
