Separatists' Last Stand

Whenever a creature or Planeswalker you control
dies, you may sacrifice Separatists' Last Stand.
If you do, create four 1/1 Droid creature tokens.
When a spell or ability an opponent controls
causes you to discard this card, if you control a {w} Plains, create four 1/1 Droid creature
tokens.
"You call this a diplomatic solution?"
— Anakin Skywalker
