Terisiare's Devastation{X}{2}{B}{B}
Sorcery
You lose X life and create X tapped Powerstone tokens. Then all creatures get -1/-1 until end of turn for each artifact you control. (The tokens are artifacts with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.")
In the end, the war had no winner.
