Shilgengar, Sire of Famine + Metalwork Colossus + Peregrin Took

Shilgengar, Sire of Famine

Metalwork Colossus

Peregrin Took

How it works

1. Cast Metalwork Colossus by paying 0.
2. Activate Shilgengar by sacrificing Metalwork Colossus, creating a Blood and a Food token.
3. Activate Metalwork Colossus by sacrificing the Blood and Food, returning it from your graveyard to your hand.
4. Repeat.

This clever loop lets you sacrifice and recur Metalwork Colossus at zero net mana cost while generating an endless stream of artifact tokens. Shilgengar, Sire of Famine provides the necessary sacrifice outlet that turns your departing Colossus into a Blood token, which Peregrin Took cheerfully amplifies by adding an extra Food token to the mix whenever tokens are created. From there, you simply cash in those newly created Blood and Food tokens to pay the activation cost required to return Metalwork Colossus straight from your graveyard back to your hand, ready to be cast for free all over again.
