Cursed Family Tome

When Cursed Family Tome enters the battlefield,
exile a creature you control. Put a copy of that creature onto the battlefield except it is a Black
Bird with flying in addition to its other types and abilities.
Non-Bird creatures that deal combat damage to
you are exiled and replaced with a 1/1 Black Bird creature with flying at the end of combat.
When this artifact is destroyed, search your
library for a creature card with mana value 2 or
less and put it onto the battlefield.
