Named Apocalypse

Destroy all opponents' creatures whose name begins with a consonant.
Exile all opponents' creatures whose name begins with a vowel.
You may sacrifice any number of creatures to add that number of mana, each of any color, to your mana pool.
If any loud noise starts to play that isn't caused by one of the players (phone notification, car honking, dog barking, person yelling, etc.) while this spell resolves, you lose the game.
