This loop is a masterclass in self-sustaining momentum, turning a simple mana dork into an endless engine of green mana and storm count. With Anger resting in your graveyard, its static ability grants every creature you control—crucially including the returning elf—immediate haste so they can tap the moment they hit the board. That speed allows Priest of Titania to generate an excess of mana based on your elf count, more than paying to recast it after Temur Sabertooth bounces it back to your hand. By repeating this cycle, you continuously trigger creature entry and leave-the-battlefield effects while generating boundless green energy.
