Something I'm seeing with this deck, is a lack of Madness, you have a ton of cards to do discarding with, and it seems almost a bit to much, since you won't be getting enough of the Madness cards.

If you can try to fit them in, look into cards like Gorgon Recluse, Reckless Wurm and Dark Withering.

Since you have Guttersnipe and Young Pyromancer, why not tossing in Shock? It's cheap to play, and if you have both a Guttersnipe and Pyromancer, for one mana you'll deal 4 damage and get a 1/1.

No problem, cause Slitherhead can work in nearly any Green or Black deck, he's easy to play, easy early blocker, then pumps what you have left afterwards.

Well, they're ideas to think on lol.

Slitherhead perhaps?

Mines more like a Swiss Army knife version of a Rakdos deck, it has alot of aggression, but also a decent amount of controling aspects and things to mess with people.

Well, if you got Zombies, why not stick in 4 Gravecrawlers, as they die, return them if you have a Diregraf or Dreg Mauler on the field.

Alright, two things I notice, one of your win conditions happens to be Mayael's Aria, since you have that, why not toss in Primordial Hydra? It gains power and toughness like crazy if it has enough counters on it. And also why not toss in a Felidar Sovereign, just to give another win condition if you can gain 10 life.

And since I see alot of mana generation, why not stick a Worldspine Wurm? You have 8 creatures for mana, and land generation cards, so it's a possibility to play.

It can find use in nearly any red deck, it's like a Searing Spear with extra kick.

Showstopper especially, if the other player has a field clearing card, play it and kill them with their own card pretty much.

Alright, did a bit of looking, maybe these cards can help.
Awaken The Ancient, turns a mountain into a 7/7 with haste, could help get the win.
Sinister Possesion, Makes something lose life for attacks/blocks.
Showstopper, play it if you know you are about to lose alot of creatures to deal alot of damage.
And last card would be Skullcrack, pretty much an easy damage card, but it also stops life gain and prevention of damage for the turn.

Just to give a couple choices and ideas.

Alright, I'm going to do some research, you want something that deals damage in particular or perhaps an Enchantment?

I did a bit more looking, and perhaps you would be interested in using a Planeswalker? In particular Domri Rade.

Rakdos return, if you think about it, you'll do about... 4-6 damage in a quick game and discard the other players hand, which by then could only be 1-2 cards. Havoc Festival if played on your turn, will cut the opponants life in half on their turn, then once it's back to your own turn, you should be able to get the kill possibly.

So to sum it up, yes, Havoc Festival.

Ah I see, well, if you do get a chance to buy cards or whatever, if you want to continue with this deck, the two cards I posted are great choices, and if you want to try it, you can get Myr Galvanizers, and whatever number of Myr for an infinite mana combo to play all your stuff.

Havoc Festival is nice in this deck yes, but, I think a better choice would be Curse Of Bloodletting, if you don't mind it becoming not standard soon. It's a card I use in my own Rakdos deck and it has won me many games.

Well, since you're doing alot with Enchantments, why not stick in Sphere of Safety?

Alright, here is some cards I did a little looking into. Carnage Gladiator, if you are not blocking, might as well let your opponent feel some pain for blocking.
Instead of Ultamate Price, it would be better putting in 2 Dreadbores, it can kill any creature, and even planeswalkers, which can be game changing at times.
Rakdos Shred-Freak, it may not have Unleash, but a 2/2 for 2 red or black mana with haste is always nice in an aggressive deck. Or you can go with Spike Jester, it's same mana cost but a 3/1.

And I suspect you won't be blocking much if your unleashing alot? Right lol?

Well, you could also replace 2 mountains and 2 forests for their Red/White and Green/White shock land equivalents to help making sure you have White mana. I would also recommend Door of Destinies, it's amazing for Sliver decks.
