Merrow Bonegnawer card art
Merrow Bonegnawer hits every graveyard at once — one activation exiles all cards of the chosen type from every opponent's yard, and looping it with something like Gravecrawler turns that into a repeatable hoser rather than a one-shot answer. The cost is a single blue mana and tapping a Merfolk you control, which is almost nothing in a deck already built around the tribe.

Ketramose, the New Dawn rewards you for casting and recurring small creatures, so Merrow Bonegnawer slots in as a combo-adjacent utility piece that strips opponents' graveyards while feeding the loop Ketramose wants to run anyway.

In Commander, Merrow Bonegnawer is a niche but real piece of graveyard hate that earns its slot in Merfolk tribal builds — the activated ability hits all opponents simultaneously, which is exactly what you need in a four-player pod. Pauper is the other format where it has legs: common graveyard-centric strategies like Dredge-adjacent lists exist, and a repeatable exile effect on a cheap creature is worth considering in the sideboard. Legacy and Vintage both have access to more efficient graveyard hate, so Merrow Bonegnawer doesn't compete there outside of tribal synergy decks. Modern falls in the same category — the card is legal but the bar for graveyard interaction is simply too high for it to see play.

Price Context

Current price

$0.22 bulk tier

At $0.22, Merrow Bonegnawer is deep bulk — you're picking it up for almost nothing. It won't appreciate unless Merfolk tribal or Ketramose-style combo decks spike in popularity, so treat it as a cheap role-player rather than a spec target.
