Ewinra, Orzhov Protegée

Whenever a creature you control dies, each
opponent loses 3 life unless they pay {3}. If they
do, create a Gold token.
Sacrifice a creature: Ewinra gains indestructible
until end of turn. You gain 2 life.
The smart members of the Orzkov oligarchy sacrifice
guards and body doubles to preserve themselves. The
ingenious ones also get rich off of it. She alone can
destroy her opponents with it.
