Ratadrabik of Urborg + Leyline of Singularity + Evil Twin

Ratadrabik of Urborg

Leyline of Singularity

Evil Twin

How it works

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