Ratadrabik of Urborg + Leyline of Singularity + Phyrexian Metamorph

Ratadrabik of Urborg

Leyline of Singularity

Phyrexian Metamorph

How it works

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