The 3 combo pieces

How to execute it

  1. Cast Mercurial Pretender by paying its mana cost. Choose to have it enter as a copy of Ratadrabik.
  2. Put Mercurial Pretender into your graveyard due to the legend rule.
  3. When Mercurial Pretender dies, Ratadrabik triggers, creating a token copy of Mercurial Pretender 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 Mercurial Pretender token instead.
