Fan of Knives

SilentPowerRare
Shivs now hit ALL enemies.
Add 4 Shivs into your Hand.

You get a permanent power that changes every Shiv's targeting to all enemies, then 4 Shivs are added to your hand. A Shiv is a 0-cost Attack that deals 4 damage and exhausts. The power itself does nothing on its own; the Shiv card checks for it when played and switches to hitting everyone. Upgrading adds 5 Shivs instead.
