Reya Mantlemorn

When Reya Mantlemorn dies, create Mantle's
Edge, a legendary black and red equipment
artifact token with "Equipped creature gets
+3/-1," "Whenever equipped creature attacks,
if that creature is named, "Reya, Revenant
Avenger", then it gains double-strike," and
"Equip {3}"
When Reya Mantlemorn dies, return it
under the battlefield transformed under its
owner's control. When it is returned, you
may attach Mantle's Edge to them.
