This clever loop relies on Agatha of the Vile Cauldron to drastically slash the activation costs of your creatures based on her power, turning otherwise prohibitive mana expenses into profit. By filtering and generating resources with Soulbright Flamekin and Signpost Scarecrow, you can easily fuel Temur Sabertooth's ability to bounce the Flamekin back to your hand. Recasting the Flamekin and repeating the process yields a net surplus of mana and infinite entry triggers, eventually letting you sink your vast riches into Agatha's own hoof-and-horn buff to overrun the table.
