Cursed Fog Machine

Cursed Fog Machine’s power and toughness are equal to the number of fog machines you have seen in your lifetime.
Whenever Cursed Fog Machine enters the battlefield, create two Fog tokens. (Fog tokens are artifacts with no abilities but are very mysterious.)
Whenever a creature attacks, you may make fog machine noises. If you do, that creature cannot be blocked this turn.
Sacrifice Cursed Fog Machine: All creatures on the battlefield are now Oozes for the rest of the game.
