Relentless Rats Discussion

Needs more Rat Colony

With only 6 Relentless Rats you need half of your total number on the battlefield to even make them 4/4s. Most of the time they will be 3 mana 2/2s. You need a critical mass of Relentless Rats--at least 20. If you want to dedicate only a small portion of your deck to the Relentless effect, then Rat Colony is much better; unlike Relentless Rats it benefits from any rat you control, including Marrow-Gnawer's tokens. Pack Rat is also superior if you have many non-Relentless Rats.

Rat Colony is strictly better than Swarm of Rats. It's also generally better than Bog Rats, Carrion Rats, Muck Rats, Nezumi Cutthroat (fear isn't worth a large power loss and "can't block", especially when Marrow-Gnawer provides fear), Pestilence Rats (Rat Colony gets +2/-2 under most conditions and costs 1 less), and Earsplitting Rats (not enough graveyard/discard synergies).

Other suggestions

Tormod's Crypt -> Nihil Spellbomb, Bojuka Bog. You can run Crypt in addition if needed, but I would use these first.

Kitesail -> Bladed Pinions, Fleetfeather Sandals.

Geth's Grimoire -> remove. Only four or so cards in this deck actually cause an opponent to discard. Since you're running Ancient Craving, might as well slot in Ambition's Cost as well.

Nightmare Lash -> Lashwrithe. Or just run both, but Lashwrithe first.

Sword of the Paruns -> Bad Moon, Adaptive Automaton, Hall of Triumph, Vanquisher's Banner, and Obelisk of Urd are all more mana efficient and consistent ways to pump your rats.

Altar's Reap -> Costly Plunder, Night's Whisper, Sign in Blood.

I'm not sure how Shriveling Rot serves the deck.

There are two Cabal Strongholds, so one needs to come out. Cycling lands--Barren Moor, Polluted Mire, and Desert of the Glorified--hedge against land-heavy draws. Some cheap utility/value lands like Zhalfirin Void, Encroaching Wastes, Mystifying Maze, or Temple of the False God might be good over some number of Swamps too.

Phyrexian Tribute -> Scour from Existence, Unstable Obelisk. I know black is bad with artifacts, but there is a reason Phyrexian Tribute is in 55 edh decks, and the other two are in over 5000 each, and it isn't just color restriction. They cover all five permanent types instead of just one, including the equally hard-for-black enchantments. Requiring two creatures to sacrifice, Phyrexian Tribute isn't even always easier to cast, and it's effect is far less flexible.

Speaking of Unstable Obelisk, more mana ramp would be prudent, like Wayfarer's Bauble, Mind Stone, and Commander's Sphere. Bontu's Monument isn't Jet Medallion, but is still worthwhile with 27 creatures.

I don't think there are enough graveyard synergies to make Living Death appropriate.

Night Dealings is slow, does nothing if the battlefield isn't somewhat favorable, can potentially get removed, makes you reveal, and can't get lands. Razaketh's Rite and Mastermind's Acquisition tutor with no fuss. If you want slow, multi-card tutoring, Diabolic Revelation, Demonic Collusion, and Increasing Ambition are reliable options. Although none feature Nezumi in their art.

Curse of Death's Hold is a bit narrow for multiplayer; I'd prefer Ascendant Evincar which will hit more enemy creatures overall while buffing your own and being a 3/3 flier.

  1. Relentless Rats
  2. Razortooth Rats
  3. Crypt Rats board wipes and hits all players so you'll want some life-gain
  4. Rotting Rats
  5. Sinuous Vermin Can get quite large. Could used after a board wipe
  6. Gnat Miser is interesting. Useful early/mid game or against controlly matchups

harbingerofduh on Damia Hand Disruption

I have a deck, Damia Discard, that has a lot of symmetrical discard because Damia allows you to recover much more easily than your opponents, and because targeted discard is less good when you have multiple opponents. I've found Necrogen Mists and Bottomless Pit to be indispensable, and Liliana of the Veil would also be pretty good if you can afford the price tag.

Extirpate doesn't make any sense in a singleton format (unless your playgroup has a lot of Relentless Rats decks running around, ha), so that's an easy cut. Wheel and Deal is also really bad in this deck - if you've been making your opponents discard, the absolute last thing you want to do is give them a free Wheel of Fortune.

I read several articles on this before making the deck. Relentless Rats is legal in multiples of 30+, so this should be too.

When ~ enters the battlefield, exile target creature or planeswalker you control and target creature or planeswalker you don't control until ~ leaves the battlefield.

Callenge: make a creature version of Relentless Rats/Rat Colony with maybe a Collected Company vibe going. Imagine a muster of all the forces of the Legion.

Rat Colony can have as many you want in a deck but the commander/edh deck builder only allows 1, but it does allow as many Relentless Rats which has the same mechanic

Looks like this problem is also apparent in standard... thanks for the hard work u guys put in I can only imagine the headaches new cards present for you and your team

Looks fun, and I wish rats were more viable. I think they will expand them more like they did zombies recently. That being said Thrumming Stone with enough Relentless Rats can get goofy.

Change Rat Colony to Relentless Rats. Then the toughness is powered up.
