This looping engine relies on Rooftop Storm to completely eliminate the mana burden of casting creature spells, allowing Ebondeath, Dracolich to continuously emerge from the graveyard for free whenever a creature dies that turn. To fuel that requirement, Woe Strider provides a reliable sacrifice outlet right on the board, letting you feed Ebondeath to the graveyard while simultaneously smoothing your draws with its scry ability. Because Ebondeath's recursive trigger only requires *another* creature to die, sacrificing it to Woe Strider instantly unlocks the condition needed to cast it again right away for zero mana.
