Skittering Precursor + Sword of the Meek + Ruination Guide + Arcbound Ravager

Skittering Precursor

Sword of the Meek

Ruination Guide

Arcbound Ravager

How it works

1. Activate Arcbound Ravager by sacrificing Sword of the Meek.
2. Skittering Precursor triggers, creating a 0/1 Eldrazi Spawn creature token.
3. When the Eldrazi Spawn enters the battlefield as a 1/1 due to Ruination Guide, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
4. Resolve the Arcbound Ravager ability, putting a +1/+1 counter on it.
5. Repeat.

This ingenious looping engine turns the humble Sword of the Meek into a recursive powerhouse by exploiting its interaction with toughness-boosting anthems. Because Ruination Guide pumps your colorless creatures, the 0/1 Eldrazi Spawn tokens created by Skittering Precursor actually enter the battlefield as 1/1s, which instantly triggers the Sword to return from your graveyard and attach itself. From there, you can feed that very same Sword of the Meek to Arcbound Ravager, triggering Skittering Precursor anew to endlessly grow your artifact creature, generate an army of tokens, and flood your mana pool with colorless energy.
