The Radahn Festivel

Target creature you control deals X damage to X
other creatures your opponents control, where X
is that creature's power. Then those creatures deal
damage equal to their total combined power to that
creature.

"Champions, welcome! The stars have aligned! The festival is nigh! General Radahn, mightiest demigod
of the shattering, awaits you! A celebration of war!
The Radahn Festival!"
