Ratadrabik of Urborg + Boonweaver Giant + On Serra's Wings + Phantom Train

Ratadrabik of Urborg

Boonweaver Giant

On Serra's Wings

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Boonweaver Giant.
2. When Boonweaver Giant dies as a legendary creature due to On Serra's Wings, Ratadrabik of Urborg triggers, creating a token copy of Boonweaver Giant that is a 2/2 Zombie in addition to its other types.
3. When the Boonweaver Giant token enters the battlefield, it triggers, returning On Serra's Wings from your graveyard to the battlefield attached to the token.
4. Resolve the Phantom Train ability
5. Repeat.

This brilliant loop relies on the constant rebirth of Boonweaver Giant to leverage a clever aura trick and a relentless sacrifice outlet. Ratadrabik of Urborg acts as the cornerstone of the engine, watching over your legendary creatures and ensuring that whenever one perishes, it leaves behind a nonlegendary Zombie copy. Because On Serra's Wings permanently bestows the legendary supertype upon the creature it enchants, Boonweaver Giant counts as a legendary creature when it dies, instantly triggering Ratadrabik of Urborg. As the fresh Boonweaver Giant token enters the battlefield, its own ability fetches On Serra's Wings right back from the graveyard, re-equipping the aura to make the token legendary once again. Finally, Phantom Train provides the necessary sacrifice outlet to send the Giant to the grave, converting each iteration into infinite death triggers and stacking endless +1/+1 counters onto the Vehicle.
