Buckminsterfullerene on Rats

I'm afraid that Survival of the Fittest isn't modern legal. Evolutionary Leap as a rough equivalent, perhaps? Also, more Swarmyard, more fun!

Rzepkanut on Mazirek Sac-Storm: The Contraption of Life & Death

1 week ago

If I had a Doubling Season, I would totally run it alongside Primal Vigor. Seems fun.

Volrath's Stronghold is great, but I happened to own it already. Not sure if its all that necessary, but its good in the deck.

Swarmyard is a good looking protection effect since Mazirek is public enemy #1, but I've never used it personally. I guess Yavimaya Hollow is better anyways.

Link your version here once you assemble it I'm curious to see how it ends up.

Bontu's Monument and Jet Medallion for cost reduction.
Vanquisher's Banner and Disciple of Bolas for card draw.
Crypt Ghast and Cabal Coffers for lots of mana mana.
Swarmyard just because.
Living Death and Patriarch's Bidding after you've been boardwiped too many times.
Wake the Dead for finisher.
Homeward Path protection against stuff like Insurrection.

I'd drop the Relentless Rats. Those are all in or nothing. Gotta run 25+ of them for it to be an even vaguely successful strategy.

I second what the other comments are saying. Drop the 12x Relentless Rats and add in 4x Chittering Rats and Ravenous Rats to keep up the hand pressure on your opponent. Swarmyard is a pretty much auto 4x of. Amazing card that only fits in this type of deck. Thoughtseize or Inquisition of Kozilek are other cards to consider, or better yet some removal like Doom Blade or Fatal Push.

If you really want the deck to get a boost, run 4x Aether Vial.

@skoobysnackz Haha, yeah, you pretty much suggested all that was already in here. xD

Marrow-Gnawer is definitely out of my budget, I'm afraid.

I used to run both Ogre Slumlord and Ratcatcher in my old Pack Rat build, but over time they proved themselves to be waaay too slow against most decks, Ratcatcher even more so (since you don't get anything out of him until turn 7). I might throw the slumlord back in, see how it works with this build, but I just can't see Ratcatcher working for me.

I like Claim a lot because most of the time it's a Pack Rat for , and though it certainly doesn't have the power of Immortal Servitude, it's just one mana, and Immortal Servitude takes five. Claim can also play Tetsuko Umezawa, Fugitive without having blue mana available. So I'm keeping it not as a reanimator, but as an additional copy of a two mana creature for one (including, now, Rat Colony), if that makes sense.

You make a good point on Profane Command not being ideal as a 4-of. Though it can end the game or get rid of pesky blockers, it takes a lot of mana to do that and I'm probably better off running just a couple. Don't want to have it in my hand all the time.

PS: I really like your deck's inclusion of Urborg, Tomb of Yawgmoth! A lot of the time I find myself annoyed that I'm lacking a necessary due to one of my lands being a Swarmyard xD Wish I had the money to put one in this as well.

PPS: One card I'm unsure of is Rotting Rats. Self-discard is nice if you build around it, but it still feels a bit counterproductive, and I no longer have any madness spells, and though it's great to reanimate things, I don't really need to be discarding them first just for that. If I were to get rid of it, I could probably use the slot for some removal spells, and that might be better. Any thoughts on that?

PPPS: Almost forgot to comment on Duress. It's nice, yeah. I could probably use something else to do on turn 1 besides playing a Typhoid Rats. I'll play around and see if I can find a spot for it!

skoobysnackz on Help with making Rat Colony ...

Here's the list I wrote up not long ago: The Plague. I think the key to making rats work is to have:

  1. Pack Rat as a 4-of, non-negotiable.

  2. Something, actually, lots of things to make your opponent discard. I would start with Ravenous Rats and Rotting Rats if Inquisition of Kozilek, and Thoughtseize are out of budget, and would probably still add one of them even if they are.

  3. Something to bring back discarded/dead rats. Return to the Ranks and Immortal Servitude seem like the best options to me. Note: Swarmyard can also be game over to an overeager opponent who doesn't pay attention to the lands you're playing.

I think if you have this covered, the rest of the deck should build itself pretty easily. My deck runs 12 Rat Colonys, I think more would be a little risky in case your opponent has Maelstrom Pulse or Echoing Truth.

Some other cards to consider are Marrow-Gnawer, Ogre Slumlord, and Ratcatcher. I know Marrow-Gnawer is a little expensive, but if you can afford it, he's probably the most efficient finisher you can get for this deck. Just the fact that he gives all rats fear should be enough in most situations, his other effect is just the cherry on top. Ogre Slumlord also puts a wrench in many opponents' plans by giving all your rats deathtouch. If Marrow-Gnawer is not in your budget, I would go with Ogre Slumlord as the finisher.

Lastly sorry for the long post, and sorry if I'm suggesting cards you already have in your list, I was pretty excited when I saw someone else was also interested in a rat deck so I just threw all the suggestions I had before even looking at your list.

xsilverwarrior7 on Ishkanah's Nope Party

Your Ishkanah looks better than mine. I have some ideas to improve.

Ashnod's Altar + Nim Deathmantle + Ishkanah, Grafwidow with Delirium = infinite spider tokens and colorless mana. Just a note here, you need to put Ishkanah in the graveyard for this to work.

Buried Alive can be useful, especially if you use Arachnoid and Nyx Weaver. Those will be the only spiders I suggest because of multiple types for Delirium.

Filth can be fun if you don't mind throwing in a non-spider.

Crop Rotation can help get certain nonbasic into play while Swarmyard can protect a spider in certain situations.

And for more aggressive decks, maybe sideboard one or two Whip of Erebos for extra pain? Great to whip back your guys (in the event you can't Swarmyard them, and you will get tons of life.
