Ratadrabik of Urborg + Boonweaver Giant + On Serra's Wings + Woe Strider

Ratadrabik of Urborg

Boonweaver Giant

On Serra's Wings

Woe Strider

How it works

1. Activate Woe Strider 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 Woe Strider ability, causing you to scry 1.
5. Repeat.

This ingenious loop turns a single giant into an endless engine by leveraging the passive enchantment of On Serra's Wings to make Boonweaver Giant legendary. Once it has that crucial status, sacrificing the creature to Woe Strider triggers Ratadrabik of Urborg to birth a nonlegendary Zombie copy, which immediately triggers its own entry ability to fish the Aura right back out of your graveyard and reattach itself. Because Woe Strider's sacrifice outlet lets you repeat this sequence at will, you get an uninterrupted stream of enters-the-battlefield and death triggers fueled endlessly by the graveyard.
