Paradox Engine + Shrieking Drake

Paradox Engine

Shrieking Drake

How it works

1. Activate all mana-producing nonland permanents you control by tapping them, adding at least .
2. Cast Shrieking Drake by paying .
3. Paradox Engine triggers, untapping all nonland permanents you control.
4. When Shrieking Drake enters the battlefield, it triggers, returning itself from the battlefield to your hand.
5. Repeat.
6. If nonland permanents you control can tap to produce at least 1, this combo nets infinite mana.

This clever loop turns the self-bouncing nature of Shrieking Drake into a perpetual motion machine, fueled entirely by the mana-producing artifacts and creatures you control. As you cast the Drake over and over, Paradox Engine triggers upon each spell cast to effortlessly untap all your nonland permanents, paying back the mana required to keep the loop going. Meanwhile, the Drake's own entry trigger forces it right back to your hand, ensuring you never run out of ammo while generating an overwhelming storm count and infinite enter-the-battlefield effects.
