Relentless Rats!?!?!?!?

[Thattallguy]

I am putting together a rat deck. So far I have 22 relentless rats and 4 thrumming stones. Any ideas for anything else I could use in this deck that would be beneficial. I don't want to rely solely on the rats.

{Relentless Rats}
{Thrumming Stone}

Don't forget to add curly brackets to create links.

I think the biggest threat to this deck is mass removal.  One {Day of Judgment} can really ruin your day.  How about a {Patriarch's Bidding}?

Maybe mana accel like {Dark Rituals}.

[Thattallguy]

22 {relentless rats}
4 {thrumming stone}

This is what I have so far. Open to ideas suggestions. Really want this deck to be fun yet competitive.

Maybe a {No Mercy}  to protect you. However the biggest issue i see is flying creatures.

[BlackJester]

Throw in some spot removal.  {Doom Blade}s, {Go for the Throat}s, {Innocent Blood}s.  Some {Ghost Quarter} to deal with {Kessig's Wolf Run}.

I have a deck based on {Relentless Rats} that I really have to get around to uploading!!!

Notable cards are {Swarm of Rats}, {Pestilence Rats}, {Typhoid Rats} and the Lord of my deck (and one of my fav cards), {Marrow-Gnawer}. For other cool rat creatures, check out the Kamigawa block.

When you get a lot of rats with {Marrow-Gnawer}, an {Akroma's Memorial} would be so funny xDD, but I think that you have a few possibilities to do this in a seriously match.
--------------------------

{Nighteyes the Desercrator} would be good with control cards like {Doom Blade} or {Thoughtseize}.
Also, some "finish" spells like {Nocturnal Raid} can help you to strike a lethal hit. But if ou prefer you can use enchants to increase the power of your rats ({Bad Moon} for example). And you need something in sideboard vs white control decks with {wrath of god} and that kind of spells, but mono black I don't know :S

EDIT: The link of Nezumi Graverobber don't works good, search it in the DB by name.
EDIT2: Fixed changing by Nighteyes the Desercrator.

Splash green with {doubling chant} and {overrun}

[BlackJester]

Splash green with {doubling chant} and {overrun}

{Doubling Chant} would be great here, since you could cast it with 6 {Relentless Rats} on the table and go get another 6.   ;D

I wouldn't recommend {Overrun} simply because it's 2GGG and slashing to get three green mana in a Black deck just isn't worth it.  Besides, if you nail your {Thrumming Stone} you'll have a hoard of enormous rats anyway.

[Mentonin]

A splash for the chant is worth it anyway

[Alpha]

With green in the deck you can include some {Strength in Numbers} and put it on unblocked rat to strike the final hit (or blocked if u want kill some creature also it gives trample).
And add a {Bloodbond March}, of course xDD
Mono black full rats you can add a {Desperate Research}.

[Mentonin]

I like {beastmaster's acension}  better

[Mentonin]

4 acension on the field and u hit with 10 rentless, they'll all be 31/31. Theyll all cost 3. Very funny

[Mentonin]

{eldrazi monument} ooks lot of fun

[Alpha]

{Aether Vial} and leave it with 3 charges (this is a free rat each turn).
