Kae'yar Deathwalker

Whenever a creature you control dies you may
pay {1}{w}{b}. If you do, create a 1/1 colorless
skeleton creature token with "{b}: Regenerate.". Activate this only once per creature.
{2}: Target skeleton you control becomes an
artifact equipment with "Equip {1}", "Totem
armor" and " Equipped creature gets +X/+X,
where the values were the skeleton's power and toughness"
