Ashmouth Hatespawn

When Ashmouth Hatespawn enters the battlefield, exile each card in your graveyard with Madness, then, for each card with a different name exiled this way, cast it from exile as though it was discarded without
paying its Madness cost. If {x} is in the
Madness cost of a card cast this way, {x} is 5.
Death is not a setback, rather a tool.
