Karumonix, the Rat King

Legendary Creature — Phyrexian Rat

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)

Other Rats you control have toxic 1.

When Karumonix enters the battlefield, look at the top five cards of your library. You may reveal any number of Rat cards from among them and put the revealed cards into your hand. Put the rest on the bottom of your library in a random order.

I know you are going more budget with this but figured I could suggest a few Rats or cards that help a chosen creature type: Ashcoat of the Shadow Swarm, Lord Skitter, Sewer King, Ratcatcher, Karumonix, the Rat King, Twisted Sewer-Witch, Skemfar Shadowsage, Kindred Dominance, Haunting Voyage, Crippling Fear, Aphetto Dredging.

I leave this in your capable hands. Do you think the deck needs more removal? Sadistic Hypnotist or Feed the Swarm. Another win condition? Altar of the Brood, Altar of Dementia, or Karumonix, the Rat King. More card draw? Phyrexian Arena, Black Market Connections, Deadly Dispute, Bankrupt in Blood, or Village Rites. (I know I suggested some of these cards already; they've worked well for me.)

Pulling from my own Rat tribal deck (Modern-ish casual, not EDH):

Karumonix, the Rat King gives you an out against lifegain-heavy decks. I don't recommend going deeper than that with poison (i.e. don't add Ichor Rats or Septic Rats), but Karumonix adds a layer to your attacks and keeps rats coming.

I haven't gotten Ashcoat of the Shadow Swarm yet, but I want to. It looks amazing. If your budget can handle it, I'm recommending it just in theoretical grounds.

I personally am not impressed with Swarm of Rats (Rat Colony is pretty much all-around better) and Pestilence Rats, but they might work better in EDH, where you always have access to a fear-granting effect. How have they worked for you?

Ratcatcher is a free tutor for a rat every turn. Highly recommended.

Memoricide is a little odd, since it can only hit one card that isn't in play. Is this a meta choice? Do you have a specific target for it that you know you'll see?

Unless you see a bunch of Voltron, Battlecruiser, or other decks with one big creature, I would diversify the removal a little bit. You have a lot of single-target creature removal. I'm a big fan of discard, so I'm recommending based on what I like at this point. Cabal Therapist, Mind Slash, and Sadistic Hypnotist turn your rats into hand removal. Feed the Swarm offers enchantment removal with a very evocative name for this deck. Try some of these in place of Cast Down or Ultimate Price or something. Also, Despise isn't great if you're just fishing. If you want a T1 discard effect, Thoughtseize is best, Inquisition of Kozilek and Blackmail are solid, and Dread Fugue is pretty good.

Following up on that, I see a good set of mass removal and graveyard recursion, and Marrow-Gnawer lets you rebuild quickly. This part looks solid.
