The 3 combo pieces

What must be in place

You control a Rogue that does not have summoning sickness and that cannot be blocked by an opponent.

How to execute it

  1. Deal combat damage to an opponent using a Rogue.
  2. Cast Notorious Throng for its prowl cost by paying {5}{U}, taking an extra turn after this one.
  3. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Timeless Witness.
  4. When the token Timeless Witness enters the battlefield, it triggers itself, returning Notorious Throng from your graveyard to your hand.
  5. Repeat.
