Shadow, Heir to Destiny

Whenever another legendary creature you control dies, you may pay its mana cost. If
you do, exile it, then create a token that's a
copy of it except it's an Aura with "Enchanted creature has each other ability
of this token." Attach that token to Shadow.
"I swear to you father, I will take on your legacy
in stride or so Carwyn have my soul!"
