Black Plague

Corrupt X (You may pay 1 life as you cast this spell to corrupt it. Corrupt it up to X times by doubling the amount of life you pay each time.)
Each player loses X life, discards X cards, sacrifices X creatures, then sacrifices X lands.
There was No grand battle, No last stand, No glorious resistance, No poetic last words, No heroes.
The city had gone out with a whimper.
