Myrkul, Lord of Bones + Cinderhaze Wretch + A Realm Reborn

Myrkul, Lord of Bones

Cinderhaze Wretch

A Realm Reborn

How it works

1. Activate Cinderhaze Wretch's second ability by putting a -1/-1 counter on it, untapping it.
2. Repeat step 1 until Cinderhaze Wretch dies as a state-based action due to having zero or less toughness.
3. Myrkul triggers, causing you to exile Cinderhaze Wretch and create a token copy of Cinderhaze Wretch that is an enchantment and loses all other card types.
4. Activate the Cinderhaze Wretch token by tapping it, adding one mana of any color.
5. Activate the Cinderhaze Wretch token's second ability by putting a -1/-1 counter on it, untapping it.
6. Repeat from step 4.
