Hex, Kellan's Companion

Description

Hex, Kellan's Companion (YWOE-14) is a Legendary Creature — Dog from the Alchemy: Wilds of Eldraine set. It has haste and a triggered ability that gives it a permanent +1/+1 whenever you cast an Adventure spell while it is on the battlefield or in exile, then exiles it with a fetch counter if it's on the battlefield. A second triggered ability returns Hex from exile to the battlefield when you cast a spell from exile while it has a fetch counter, enabling recurring battlefield presence tied to Adventure and exile interactions.
