Liliana, Untouched by Death + Rooftop Storm + Ratadrabik of Urborg + Shapesharer

Liliana, Untouched by Death

Rooftop Storm

Ratadrabik of Urborg

Shapesharer

How it works

1. Activate Liliana's third ability by removing three loyalty counters from it, allowing you to cast Zombie spells from your graveyard this turn.
2. Activate Shapesharer by paying 2, causing it to become a copy of Ratadrabik until your next turn.
3. Put the original Ratadrabik into your graveyard due to the legend rule.
4. Each other copy of Ratadrabik triggers, creating a nonlegendary token copy of Ratadrabik that is a 2/2 Zombie in addition to its other types.
5. Cast Ratadrabik from your graveyard by paying 0.
6. Repeat from step 3.
