Teachings of the Dead

Whenever a creature you control dies, choose one ability (keywords like flying or trample are abilities)
that it had. Another target creature you control
gains that ability for as long as the creature the
ability came from remains in your graveyard.

the greatest witches to ever live in only nine months."
