Varna Ragna-Arm

Haste, menace
Whenever a non-token creature with Boast dies,
exile it under Varna Ragna-Arm. Varna gains indestructible until end of turn. Then if three
or more creatures are exiled under Varna, create
a 4/3 zombie copy of the exiled creature except
it doesn't have Boast.
—Varna has the boast abilities of all creatures
exiled under it, except it costs black mana.
