Whenever The Ghoul or another nontoken Zombie or Mutant you control dies, target player gets two rad counters. If that player is you, create a Treasure token.
The Ghoul is a mono-black aristocrats/sacrifice deck that profits whenever your Zombies and Mutants die. Each death hands out two rad counters, which mill the target and drain life on their next main phase, while pointing them at yourself nets a Treasure to ramp into bigger threats and reanimation. You grind value through sacrifice loops, dump your graveyard with rads, and reanimate or close out with drain payoffs.
Repeatable rad counters provide incremental mill/life loss across the table for free
Treasure generation from self-targeting accelerates mana and graveyard fueling
First strike makes a cheap 3-mana commander a relevant attacker and blocker
Deep mono-black tutor, recursion, and sacrifice support
Rad counters synergize beautifully with self-mill reanimator strategies
Damage output via rads is slow and easily out-paced by faster combo or aggro decks
Relies on a steady stream of nontoken Zombie/Mutant deaths to keep value flowing
No built-in evasion or protection beyond first strike
Mono-black means weak interaction against enchantments and resilient artifacts
Self-milling rads can accidentally bin key cards if undisciplined
