Dance of Chaos

(You may cast a legendary sorcery only if you control
a legendary creature or planeswalker.)
Each player may search their library for a card,
reveal it, and put it into their hand. Then Dance
of Chaos deals damage to each creature and
player equal to the total combined mana costs of
the revealed cards.
"Dance into the fire, that fatal kiss is all we need..."
