Ratadrabik of Urborg + Boonweaver Giant + In Bolas's Clutches + Phantom Train

Ratadrabik of Urborg

Boonweaver Giant

In Bolas's Clutches

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Boonweaver Giant.
2. When Boonweaver Giant dies as a legendary creature due to In Bolas's Clutches, 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 In Bolas's Clutches from your graveyard to the battlefield attached to the token.
4. Resolve the Phantom Train ability
5. Repeat.

This clever loop revolves around turning nonlegendary creatures into royalty so Ratadrabik of Urborg can constantly resurrect them as 2/2 Zombies. By enchanting Boonweaver Giant with In Bolas's Clutches, the Giant becomes legendary, satisfying Ratadrabik's condition when Phantom Train sacrifices it to the graveyard. The newly created Boonweaver Giant token then enters the battlefield and its own triggered ability immediately fetches In Bolas's Clutches back out of the graveyard to re-enchant the token, setting up the exact same sacrifice condition for Phantom Train all over again.
