How it works
Cast Doppelgang by paying 15, creating five token copies of Zealous Lorecaster and of the four mana-producing permanents.
When the Zealous Lorecaster tokens enter the battlefield, they trigger, returning Doppelgang and up to four other instant or sorcery cards from your graveyard to your hand.
Activate seventeen of the mana-producing permanent tokens by tapping them, adding at least 15.
Repeat.
Once you have infinite tokens and mana, you may instead target any other permanents using Doppelgang.
