Bargain With Madness

Each player exiles the top ten cards of their
library. Starting with you then alternating each
cast, each player casts all nonland spells they own
in exile in a random order without paying their
mana costs. All spells with effects that target have
their targets chosen randomly.
Exile Bargain With Madness.
A bottomless curse, a bottomless sea,
source of all greatness, all things that be.
