Whenever you sacrifice a permanent, put a +1/+1 counter on Juri, Master of the Revue.
When Juri dies, it deals damage equal to its power to any target.
"Sure, the invasion was violent, but where was the beauty? As an artist, I had to intervene."
Juri's first ability doesn't allow you to sacrifice any permanents. You'll have to find another way to do that.

For Juri's second ability, use its power from when it was last on the battlefield to determine how much damage is dealt. If that power was 0 or less, Juri deals no damage.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
