The 2 combo pieces

What must be in place

There are four permanents on the battlefield that can collectively tap to produce at least {2}{G}{U}.

How to execute it

  1. Cast Doppelgang by paying {15}{G}{U}, creating five token copies of Timeless Witness and of the four mana-producing permanents.
  2. When the Timeless Witness tokens enter the battlefield, they trigger, returning Doppelgang and up to four other instant or sorcery cards from your graveyard to your hand.
  3. Activate seventeen of the mana-producing permanent tokens by tapping them, adding at least {15}{G}{U}.
  4. Repeat.
  5. Once you have infinite tokens and mana, you may instead target any other permanents using Doppelgang.
