The 3 combo pieces

How to execute it

  1. Cast Undercover Operative by paying its mana cost. Choose to have it enter as a copy of Ratadrabik.
  2. Put Undercover Operative into your graveyard due to the legend rule.
  3. When Undercover Operative dies, Ratadrabik triggers, creating a token copy of Undercover Operative that is a copy of Ratadrabik but is a 2/2 Zombie in addition to its other types.
  4. Repeat from step 2 using the Undercover Operative token instead.
