The Price of Cowardice

Target player chooses a creature they control that
did not attack or block this turn. If another
creature they control attacked or blocked this turn
they must sacrifice the chosen creature.
Atonement {w}{r} (If this card would be exiled from
your graveyard you may choose to pay {w}{r}. If you
do, create a token that is a copy of the creature
sacrificed for this spell, except that it's a 1/1 White
Spirit in addition to its other types and colours.)
