Braid of Fire is definitely tempting. Xantcha is an amazing sink for this card. My only concern would be how long the game lasts. Two mana is such a low investment that it might be worth putting into the deck anyways. Also would make a stronger case for Pyrohemia getting added back into the deck too!

As far as Vampiric Link goes, I think you're spot-on with your analysis. I don't think the lifegain offsets the potential of getting 2-for-1'd and once my opponents know that I'm gaining life for every Xantcha activation; they will probably stop doing it. It also would be a nonbo with 3 cards currently in the deck (Sulfuric Vortex, Havoc Festival, and Rampaging Ferocidon). Along the same line of thinking, I considered adding Phyresis into the deck. However, since it would be the only source of infect, she would either need to attack the same enemy twice or have someone pump 15 mana into her activated ability before she (or the enchantment) gets removed. Alternatively there could be a damage doubler on the battlefield, but I think that's bordering on thinking too wishfully.

Adding in Braid of Fire is really tempting but also hard to slot in. As I mentioned in the update section, I'm trying to add more card draw, another boardwipe (Pyrohemia or Chain Reaction?), and a land. You could somewhat make an argument for Braid of Fire being card draw with Xantcha, but that might be stretching it too much. I'm also looking for cuts in the deck so that I can include those categories of cards; but I love every card that's currently in there. Thinking Crown of Doom even though it encourages attacks and potentially turns Xantcha into a 3 turn kill instead of a 5 turn. Let me know what you think!

Gleeock - Yeah, thankfully it's Friday and I'll have some more time to be able to give this deck a critical look this weekend! Currently looking at Pestilence, Pyrohemia, Neheb, the Eternal, Crawlspace, Diabolic Intent and Chain Reaction for cuts and looking at Blasphemous Act, Fraying Omnipotence, Dismember, Bloodchief Ascension, Master of Cruelties, Virtus the Veiled and Tree of Perdition for adds. Not 100% sold on any of these yet; but they're all strong considerations!

I see now! I LOVE that idea. I actually glossed over those two cards when I saw your deck the first time around, now I wish Xantcha was Jund. The way that you're running your deck is initially how I was planning on building mine. I just can't guarantee that they'll have enough creatures to attack with and there don't seem to be a lot of cards in Rakdos that give your opponents creatures (for a good deal); I've counted maybe 5 or so. I think redirect spells are a great addition to your deck, whereas I think my deck isn't built to utilize them to their potential.

Jimmy_Chinchila For some reason I didn't even give these cards a second thought! I was too hyperfocused on the group slug aspect of the deck to really even consider a lot of the solid Rakdos damage dealers on their own. I think I'll shy away from Malignus because I don't have any way of protecting it, giving it haste, or giving it any sort of evasion. At 5 mana, it's a pricy investment considering all that could go wrong. The other three, on the other hand, I really like and am strongly considering adding to the deck. Virtus the Veiled has the same issues as Malignus, but at 3 mana it feels much more reasonable to include. Tree of Perdition doesn't care about blockers, which is a wonderful upside. And Sorin Markov might as well be a sorcery since you can activate it as soon as it comes down. I think I'll try and order Tree & Virtus and hold off on Sorin at the moment because of the price, but he is a strong consideration for the deck. Thank you!

t3hdarkness you made some really good points.

Piranha Marsh was in it originally so I could recur it infinitely with Animate Dead and Worldgorger Dragon. I realized that it was kind of useless since at that point I would most likely have infinite mana anyways to kill with Xantcha.

Sands of Time is just another way to change the game a bit and potentially combo off with Strionic Resonator.

I agree with your thoughts on the one and done kind of spells so I got rid of them since they didn't really seem to do much even in the situation in which they would be good in.

The plan with the enchantments were to put them on Xantcha, Sleeper Agent since she can't attack her owner so I don't think that they would be inherently bad.

I was using Chain Reaction as a budget replacement for Blasphemous Act before but I realized that this price point it doesn't seem to make much of a difference. And really good call on the mana acceleration since I will pretty much always have a way to draw cards.

And finally, the win-con is something that I've struggled with in my decks a lot so far. For this deck I was thinking that I would be able to use Xantcha, Sleeper Agent 's ability to win through infinite mana which is why I put a couple ways in the deck to make it, although I don't think that there is enough and or it's not reliable enough since I would have to have a sac outlet to win anyways with Xantcha. So I guess the game plan is to play the more political game through the early stages and not seem like a threat and then finish off people with Xantcha, Sleeper Agent and/or Torment of Hailfire.

I personally don't like too many one an done effects. Rakdos colors have a lot of trouble with recursion of enchantments and non permanents without warping the deck to support them so I have a few cuts to suggest.

Piranha Marsh hurts you with that tapped land than it will your opponent's one life.

Sands of Time is cute, but since mana burn isn't part of the game any more it might no do very much. Its still probably fine if you only want to hit creatures.

Sudden Impact Is probably not good enough unless your meta is full of guys that draw their whole deck and combo off. Most of those decks win at instant speed anyway so it still doesn't really help. Supernatural Stamina and Undying Evil are equally small without some recursion effect. In a pinch you can add Charmbreaker Devils, Isochron Scepter, or Toshiro Umezawa. If you want to choose who lives and who dies while politiking on a bigger level try Cauldron of Souls.

Some of your enchantments don't do much either Bestial Fury doesn't stop the creature from hitting you while Errantry and Unnatural Hunger pretty much guarantees whatever creature you enchant will only hit you.

Blasphemous Act will usually be more damage for less mana than Chain Reaction. Only because you're running Xantcha, you can probably replace any of your card draw spells with mana acceleration.

There is one more problem I noticed, but it might just be a matter of deckbuilding philosophy. What's your win-con? How do you foresee this deck finishing the game?

Energy Bolt is a tad weak. You should run Chain Reaction or perhaps Comet Storm instead as that hits far many more things, therefore gaining you more health from the life link. Norn's Annex and Peacekeeper seem a bit weak too as with all the mass damage spells you have access to your opponents shouldn't have any creatures to hit you with. Also due you the life link your life total will be high enough that you can just take the hits.

Played against a variety of commander decks, and I think I've accomplished almost all of your achievements :)
1) Done.
2) Used Izzet Signet.
1) Essence Scattered The Scarab God (playing against Dimir Zombies)
2) Used Chain Reaction.
1) Does it count if your opponent is land screwed and scoops?
2) Wish there was more tutors, but used Eyes of the Watcher to control draws to the point where cantrips were able to draw all of the Jeskai cards.
3) Officially, I didn't rebound it (how do you do that, anyway?) but I did copy it, so I hope that counts.
ULTRA HARD: 1) Nope, still trying to do this :)
2) Actually, this is pretty easy. I used Soulfire Grand Master and Chain Reaction against a Dimir zombies deck. There were ~7 actual creatures but 10 2/2 black zombie creature tokens, so....I think this combination is actually pretty easy to obtain.
Fun challenges Em9500!

Hi, I was looking at the deck and have a few suggestions.

Keeper of Keys - This card kind of makes you a target for being the monarch, so I'm not sure if I'd run it. Then again, you are playing Vial Smasher the Fierce, so you should be used to that...

Elixir of Immortality - I'm not sure how this card ended up in your list as it just seems kind of bad. The only reason people play it is to protect their graveyard from being exiled, but with out any tutors (like your deck), shuffled into your deck is about the same as exiled. If you're running this for the life gain, I would strongly suggest Sangromancer instead.

Bontu's Last Reckoning - I know it seems like a 3 mana boardwipe, but it often costs you far more mana, especially in the late game when you can lose over 10 mana easily. I'd play Crux of Fate, Nevinyrral's Disk, or Chain Reaction as effective (not to mention cheap) low cmc wipes.

Steam Augury - This is a way worse Fact or Fiction, as fact or fiction gives you the better pile while steam augury gives you the worse (also if you can convince someone to give you all the cards in fact or fiction it's far less risky).
