Fiddlesticks, Primordial Fear

When Fiddlesticks enters the battlefield, destroy all other creatures.
If a card would be put into a graveyard from anywhere, exile it instead.

{1}: Fiddlesticks becomes a copy of target creature in exile but retains its name, type, and other abilities. You may activate this ability any number of times. Each additional activation costs {1} more than the previous one. (Abilities from all copied creatures remain.)
