This clever loop relies on Jaheira, Friend of the Forest to turn every new token you make into a mana source, allowing them to tap for green mana right away. Peregrin Took ensures that whenever Ant Queen creates a 1/1 Insect, you also get an extra Food token along for the ride, and since Jaheira makes those tokens tap for mana, you can easily filter it to pay for Ant Queen's ability again. Once you have an endless swarm of creatures and Foods, you can sacrifice three Foods to Peregrin Took's activated ability to draw your entire deck, while Hammer of Purphoros stands ready to give your new tokens haste so they can charge straight into battle.
