Swarm of Rats Discussion

I see you want cut ideas based on your comment on my wall. As such....

Butcher of Malakir - Too expensive to be impactful. Would rather have Grave Pact or Dictate of Erebos if you still wanted to keep it

Gnat Miser - Weak static effect and doesn't do much other than being a tekashi69 (a rat :P)

Sinuous Vermin - Being or not being a monsterous, it is weak. Not worth a slot.

Swarm of Rats - Potentially big dude with no trample, you already have 1 or 2 of these, redundancy is not needed. I don't even think the others are. They seem win-more.

Typhoid Rats - Is cute, but 1/1 deathtouch with no way to abuse is ripe for cutting.

Bad Moon - Definition of win-more. Anthem helps opponents too, weak static effect. Not worth it at all.

Gravepurge - Eh, there is much better recursion in black if you are so inclined.

Cast Down - Meta dependent, but I would go with Go for the Throat

You could add in some more relentless rats or some of the suggestions I recommended.

Coffers is the primary card you should add if you can, SO much ramp. But I'm biased because I have a deck based on it. Nykthos, Shrine to Nyx would help you ramp out alot too!

Reply here instead of on my wall so I can keep track of everything :)

Slaughter Games , although not very widely used, could also cause some problems in this deck. I don't know if you are making this deck on a budget, but there seems to be a lack of removal in this deck (like Dismember , for example). If you want to go a more tribal route then maybe Coat of Arms could work, as well as Cavern of Souls , even though COS is pretty costly. If you want to, you could also throw Thrumming Stone in there for Rat Colony . Relentless Rats is also another card like Rat Colony , for even more rat fun. Swarm of Rats also exists for a beefy rat creature. There are a bunch more cards I could name off, but you could probably find what you need on the wizards of the coast card finder.

Why not Swarm of Rats as a commander instead?

I made this a while back: Rat Heavy Discard. I haven't really worked on it much lately, as I've been focused on my flier deck.

It's since been dismanteled and turned into a pure discard deck. I've been wanting to go back to it being a full rat deck. It was more fun that way. Excited about Rat Colony.

I feel like it's what I always wished Swarm of Rats was, and a little cherry on the top with being able to have any number of 'em in the deck.

The extra Rat Colonys will make great place holders as we wait anxiously for a return to Kamigawa in hopes for new rats

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.

Swarm of Rats is the best choice of PDH

Concise list of considerations:

-/+ Dump Mind Twist and add Torment of Hailfire HOLY CRAP, do I love this card. It gets around so many things plus it hits every opponent.

Let's talk about your mana base for a second...

Thirty two lands? Even for a very cavalier spell slinger deck, that is a very low amount to play. I play a Shu Yun, the Silent Tempest deck on 36 and struggle some times to reach a critical mass of mana/spells. Don't fall into the trap of "I'll cut a land for this cheap spell; it'll be fine." Again, math and probability will not be on your side in the late game, not unless you're willing to invest in Nykthos, Shrine to Nyx or Cabal Coffers. An alternative might be to run Crypt of Agadeem but it's really no substitute for those lands.

Lastly, jam a Bojuka Bog or a Scavenger Grounds or both in there for graveyard hate, along with your choice of Strip Mine, Ghost Quarter, and/or Field of Ruin because if you can't have your Crypt or Coffers, why should they?

Hope this helps, good luck!
