This wicked loop begins by using Agatha's Soul Cauldron to exile Hateflayer from the graveyard, granting Yurlok of Scorch Thrash the ability to shoot targets with its own power. Because Zirda, the Dawnwaker discounts activated abilities by {2}, Hateflayer's untap-and-shoot activation cost is reduced from its heavy toll down to just a single red mana. This lets Yurlok tap for black, red, and green mana, spend that red to untap and deal damage, and repeat the process to blast opponents into ash. Best of all, Yurlok of Scorch Thrash's own mana-draining punishment turns the unspent mana left in your opponents' pools into lethal life loss!
