Ratadrabik of Urborg | Leyline of Singularity | Stunt Double

Cards

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

This combo produces a mandatory infinite loop that'll cause the game to end in a draw if it isn't interacted with.
