This clever loop relies on enchanting a creature with Freed from the Real so that tapping it for mana generates more than enough resources to fund its own untap ability. Leyline of Abundance bridges the gap by supercharging your mana production, turning any color-producing tap into a surplus of green mana. To tie it all together, Song of Freyalise grants your creatures the necessary tap ability to get the engine running while also setting up a massive final chapter. Once you've generated infinite green mana, you can easily sink it back into Leyline of Abundance to cover your board in an arbitrarily large number of +1/+1 counters.
