Ancano, Thalmor Advisor

The first instant or sorcery spell you cast each
turn has casualty 1. (As you cast that spell, you
may sacrifice a creature with power 1 or greater.
When you do, copy the spell and you may choose new
targets for the copy.)
Whenever another creature you control dies,
Ancano, Thalmor Advisor gets +1/+0 until end
of turn.
