Ratadrabik of Urborg + Leyline of Singularity + Clone

Ratadrabik of Urborg

Leyline of Singularity

Clone

How it works

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