I would suggest these revisions to the mainboard: +4 Phyrexian Crusader -4 Scar


-2 Swamp +2 Memorial to Folly


-4 Swamp +4 Inkmoth Nexus (I know this is a budget deck, but I believe this will receive a reprint soon, and while 1-2 copies is expensive, it won't break the wallet)


-2 Septic Rats +2 Ichorclaw Myr


-2 Blowfly Infestation +2 Nest of Scarabs


+1 Skithiryx, the Blight Dragon -1 Virulent Wound

CardTyrant! I love this deck and decided to build it myself with a few alterations after playing it with my group. Have you considered Altar of the Brood for an instant speed table library mill? With all your single creature pump spells, an infect creature like Septic Rats could also be a welcome addition instead of something less impactful like Typhoid Rats or Rancid Rats. You can even just have it ping people to fatal infect damage using Thornbite Staff after it gets big enough! That especially helps after the anthem effects(i.e. Caged Sun, Door of Destinies, Eldrazi Monument, etc.) makes it so Marrow-Gnawer + Thornbite Staff no longer kills your rats to enable the infinite combo. I also really enjoy Torment of Hailfire with all the mana we're generating. There are a couple more things i've changed in mine, so please let me know what you think! Here's mine.

Sorry about the rather late reply, but here it goes!

@lukas96 I just want to point out that the Midnight Banshee + Kulrath Knight lock out combo is one of the win cons in this deck; assuming you're facing non-black decks. Also this deck is meant to be a foundation to build off of, you make the changes you believe are required for your playgroup; even if that means messing with the mana base!

@DemonicExecuter This question is always hard, and tends to be heavily affected by your playgroup. If your playgroup doesn't abuse flying creatures, you could probably get away with replacing 2-4x Plague Stinger for 2-4x Ichorclaw Myr; otherwise I wouldn't bother with Ichorclaw Myr. On the other side, replacing the 4x Septic Rats for 4x Phyrexian Crusader should be a safe bet in all situations (same CMC, same stats, better effects). Finding the proper card to replace with Skithiryx, the Blight Dragon is kind of tricky, but I'd say 1x Kulrath Knight. I honestly would say as awesome as it sounds, a 2BB Black Sun's Zenith would eliminate 14 out of the 22 creatures in this deck (if un-buffed by Hand of the Praetors); not to say it couldn't work, but you'd have to build with it in mind.

@ShadowFire1 this question really boils down to Contagion Engine vs Contagion Clasp - I'd say the clasp wins out simply because it's faster and doesn't have the potential of clogging your hand as much in the early stages; its a 2 mana Scar that will later be used to proliferate. The 4 extra mana on the engine changes the targeted -1/-1 to apply to all of a target player's creatures, which just feels more clunky than helpful imo.

Remove the Flensermite for 3 more Plague Stinger and another Septic Rats.

@pints34 another user asked a similar question above. I'd replace 4x Septic Rats for 4x Phyrexian Crusader; in my opinion the protection and first strike outweigh the potential -1/-1 in stats when attacking. Some would say Ichor Rats, but I find the guaranteed poison counter upon entering the battlefield too good to pass up (due to proliferate).

As for Skithiryx, the Blight Dragon, replacing a Plague Stinger is probably the safest choice. You could replace a Kulrath Knight since it has the same converted mana cost and wouldn't affect the curve, but it's also one of the keys to locking your opponent out of the game. Ultimately the choice is yours.

@PickleNutz Happy you enjoyed piloting the deck, I find it shines the brightest in multiplayer formats. I want to note that I haven't scrapped or lowered the potency of my U\G infect deck, I simply play other decks against them like D&D: Dragons and Druids & GW Tron: Wrath of the Titans.

Feel free to delete my first post *

Ratta Tat Tat Tat. Dont forget Pack Rat!

Lands:

Swarmyard seems perfect too.

Some more tribal/creature pump:

Metallic Mimic for counters on all of your rats and Adaptive Automaton for a similar lord effect. Akroma's Memorial, Stoneforge Masterwork, Eldrazi Monument, Bad Moon

Answers:

Attrition, Eliminate the Competition, Mutilate

Card Draw:TBD!!!

Ramp:

Liliana of the Dark Realms, Sol Ring, Black Market

Rat Creature Options:

Ink-Eyes, Servant of Oni, Crypt Rats, Throat Slitter, Patron of the Nezumi, Plague of Vermin, Pack Rat

INFECT:

Ichor Rats, Septic Rats

Potential Cuts (In my opinion):

Prototype Portal Confused on why this is here. Rhystic Tutor Will almost always be countered in multiplayer. Geth's Verdict Better options for targeted removal Murder Howling Mine Black doesnt want to help everyone. Phyrexian Arena FTW.

Thanks Daedalus19876,

I've both Coat of Arms and Bad Moon in this deck, I like Bad Moon due to it making everything bigger. Honestly this being my only mono black deck, its most likely the only deck I'll use it in.

I have swapped:

  1. Ichor Rats --> Smallpox
  2. Septic Rats --> Innocent Blood
  3. Swamp --> Bone Splinters

Really wanting to swap Urborg, Tomb of Yawgmoth for Contamination, I didn't even know it existed!

Thanks for the suggestions!
