Marrow-Gnawer Discussion

Kogarashi on Can I activate Marrow-Gnawer's ability ...

You can remember what Protection covers by the acronym DEBT. Something with protection from [characteristic] can't be:

  • Damaged

  • Enchanted, Equipped, or Fortified

  • Blocked

  • Targeted

by anything with [characteristic].

Marrow-Gnawer 's rat sacrifice is a cost. Costs never target and are never prevented by protection. If instead the ability read ": Sacrifice target rat. Create X 1/1 rat tokens..." then protection would apply (note in the hypothetical that the sacrifice portion is after the colon, with the rest of the ability's effect, rather than before the colon with its cost).

Speaking from experience, what you need to watch out for are effects like on Angel of Jubilation , which prevents you from sacrificing creatures to activate abilitys. That shuts down Marrow-Gnawer decks.

I'm working on a Rat tribal commander deck with Marrow-Gnawer as the commander, and I'm wondering about how his activated ability would work with Akroma's Memorial . It's the cost that requires a creature be chosen, not the ability itself, and it says "Sacrifice a Rat," not "Sacrifice target Rat." Would I still be able to use his ability or would the protection from black prevent me from doing it?

Marrow-Gnawer to create a bunch of rats?

I highly recommend Thornbite Staff for Marrow-Gnawer , it allows you to go infinite with rat production. I run a very similar deck The Pied Piper if your interested in comparing. Mine seems to have consistency issues, at least in one v. one games: just not enough big tempo plays. I'm curious how yours fairs?

Daxos the Returned is High Power I believe. My deck list on here is outdated, I'll try to update it soon.

I play other decks that are tiered like Kaalia of the Vast (High Power), Ghoulcaller Gisa (Mid Power), Marrow-Gnawer (Mid Power), Kozilek, Butcher of Truth (Mid Power).

Daxos the Returned is at least a Tier above those decks, and Kaalia is not High Power, she should be Mid.

may i suggest a card i recently found to exist and immediately fell in love with? Faces of the Past , also i like that its cheap af. Its great in tribal, untapping and with sac engines. Imagine Marrow-Gnawer for infinite rats, or Krenko, Mob Boss with a Goblin Bombardment for infinite everything. delightful. It is a bit hard to justify it in this deck with only a goblin bombardment (as a sac engine), but it is on theme, and your tribal swarm does exist. Also, Spawning Pit exists, is on theme, and with token doublers in this deck, goes infinite with earth craft and other cool cards.

Collected Company and Aether Vial seem strange here, they're only helping cheat on small amounts of mana when you could just run more card draw and ramp in their place, doing effectively the same thing but without the chance of being dead cards. CoCo can easily whiff in this deck and is best in modern when more than 2/3rds of your deck can be played, like elves/humans/spirits, and aether vial gets one extra rat into play each turn but they have no ETB effects other than buffing, which is what that card is very good for exploiting (humans and spirits in modern again). I would add more ramp, card draw, and ways to find Thrumming Stone and Marrow-Gnawer since those are by far the most powerful effects in a rat deck. Another option is to just run Marrow-Gnawer as the commander and play cards like Caged Sun , Extraplanar Lens , and Cabal Coffers / Cabal Stronghold to double your mana. If you want to stick to green, or decide to add white with Karador, Ghost Chieftain , you can add in Zendikar Resurgent and Mirari's Wake to also double your mana, resurgent giving you extra draw also to slam rat after rat. White also gives you access to Enlightened Tutor to search for thrumming stone, which is powerful but not necessary if you want to keep it budgeted. Good luck!
