This loop relies on Emiel the Blessed constantly exiling and returning Garna, the Bloodflame to handcraft a self-sustaining engine of recursion and discard. Each time Garna enters the battlefield, her triggered ability scoops up every creature sent to your graveyard earlier that turn, turning your discard pile into an easily accessible revolving door. To fund Emiel's blinking ability, Skirge Familiar steps in as the mana engine, letting you cheerfully pitch those returned creature cards to generate black mana on demand. As long as you have enough creatures flowing through the graveyard, this trio smoothly recycles your threats while generating infinite black mana and endless entry triggers.
