This charming loop hinges on a clever identity swap between Hell's Caretaker and Body Double during your upkeep. Because Body Double can enter the battlefield as a copy of any creature card in your graveyard, it chooses to enter as a copy of the recently sacrificed Hell's Caretaker, enabling you to sacrifice the new copy to return the original Hell's Caretaker back to the field. Meanwhile, Kratos, God of War provides passive support by granting haste to all creatures, ensuring that the resurrected pieces are immediately ready to tap and keep the cycle spinning. By endlessly looping this resurrection process, you generate infinite entry, leaving, sacrifice, and death triggers to fuel whatever win condition your heart desires.
