How it works
Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
Activate Phyrexian Altar by sacrificing Worldheart Phoenix, adding one mana of any color.
Cast Worldheart Phoenix from your graveyard by paying .
Worldheart Phoenix enters the battlefield, triggering Intruder Alarm, untapping all creatures.
Repeat.
This brilliant loop leverages Intruder Alarm's static ability to untap all creatures whenever one enters the battlefield, turning every rebirth into a total reset. You kick things off by tapping Jegantha, the Wellspring for its colorful five-mana output, which is then fed into Phyrexian Altar by sacrificing Worldheart Phoenix. That sacrifice puts the Phoenix into your graveyard, perfectly positioned to be recast straight from the graveyard using that exact five-color mana. When Worldheart Phoenix re-enters, Intruder Alarm triggers to untap Jegantha, the Wellspring so you can tap it all over again for an infinite cascade of mana, entries, and sacrifices.
