As long as your life total is less than or equal to half your starting life total, Myrkul, Lord of Bones has indestructible.
Whenever another nontoken creature you control dies, you may exile it. If you do, create a token that’s a copy of that card, except it’s an enchantment and loses all other card types.
The last ability creates a copy of the card as it last existed in the graveyard, not of the creature as it last existed on the battlefield.
