Phyresis on Nekusar, the Mindrazer is just damn dirty and evil.

I forgot to say that I put Phyresis on the maybeboard because I believe it's a good card for the deck, but I also don't want my friends to hate me (at least not that much)

First, welcome to the world of Magic deckbuilding!

Based on my own experience with Nekusar, I would recommend cutting Font of Mythos and cards like it. On paper, it seems like they should be helpful, but, in actuality, they hurt more than they help. Nekusar is explosive, but easy to answer - after all, you're assisting your opponents in their finding checks to Nekusar.

Think of it this way, in a single round with four players, Font of Mythos gives you two cards, while giving your opponents six. While no single player gets card advantage relative to one another, the collective enemies are gaining vastly more cards than you. These cards require additional work to make effective and, even then, the extra cards generally help an opponent more than a couple instances of damage.

Curiosity and Helm of the Ghastlord are solid cards with Nekusar, allowing you to draw whenever opponents do. Ghastlord has the added advantage of causing them to discard whatever cards they draw.

If you run either, Niv-Mizzet, the Firemind is a solid choice, as it goes near-infinite with either of the above.

If you hate your friends, Phyresis can end games quickly--but this will get you in trouble in casual games, so I generally recommend against it.

Lightning Greaves and Swiftfoot Boots are both solid - Nekusar gets hated off the board pretty quickly, so it is important to protect him.

No Mercy is a solid Black pillowfort card. Smoke is another decent card, slowing down your opponents.

Sigil of Sleep turns your wheel effects into mini Cyclonic Rifts.

I would be sure to move Library of Leng from maybeboard to mainboard.

Hope some of that helps!

K4m4r0 I really like that idea, and I think Phyresis is the perfect alternate wincon. Once I see how that plays, I will see about adding in more. Don't want to draw too much hate, haha.

OK, consider the following changes. Obviously you'll need to consider the budget you want to keep with this deck. I'm looking at options to bring up the kill speed for this deck. If you really want to hit hard and hit fast, then you need not worry about you own life total early in the game. I know what you're going for in this deck and I think you should look at this dekc from a different perspective. I'm not talking about play styles. I'm working with your aggressive beatdown style. I'm talking about shifting strategies in mid-game. In the early game you go all-out and hit as hard and fast as possible. Get the kill by turn 4 or 5. Once you've taken out the primary threat, you shift strategies. Change your approach and work on recovery and defense, shift to a midrange gameplay.

Ditch that crappy Putrefax. The "sacrifice at the end step" is too much of a hinderance for 5 mana. It it were cheaper, maybe, but nope it is just crap.
I really like Elesh Norn, Grand Cenobite but the mana cost is too high for the early game. Not sure on this one.
I also think you should reconsider keeping the Lost Leonin since he's cheap and hits the field early. He's also a great pump target.

Better infect creatures:
Contagious Nim
Cystbearer
Ichorclaw Myr
Mycosynth Fiend
Necropede
Phyrexian Digester
Relic Putrescence - screw your mana rock.
Skithiryx, the Blight Dragon
Whispering Specter

Pump for the kill:
Invigorate - Because we don't care what their life total is.
Tainted Strike - Surprise!
Snake Cult Initiation - 3 poison counters at once.
Glistening Oil
Giant Growth, Mutagenic Growth, Titanic Growth, Might of Old Krosa - The classic pump tactic.

Let's consider toolbox utility cards:
Azorius Guildmage - Because screw your activated ability. Counter a planeswalker ability and watch the looks on their face.
Simic Guildmage - Imagine moving the Rancor or Phyresis after blockers have been declared but before the damage phase.
Prowling Serpopard - Nope, I'm gonna get my creatures.
Melira, Sylvok Outcast - Make the game one-sided.
Lightning Greaves - An additional set of Swiftfoot Boots. Yeah, I know shroud means that you can't pump, but there are ways around that.
Unburial Rites - Here it comes again.
Virulent Wound - Poison and removal.
Pistus Strike - Poison and removal.

There are some -1/-1 counters decks based around Hapatra or Atraxa. Since the infect creatures deal combat damage as whither, we can use that to our advantage.
Hapatra, Vizier of Poisons - Put those -1 counters on opponent's creatures to work making tokens.
Phyrexian Hydra - This gets just stupid with Hapatra, Vizier of Poisons.

Lands you may have missed:
I know we've talked about this in the past, but I think you should really consider getting the shock lands. A quick check of the card prices on TCGPlayer puts the shocks at about @10-15 each. Totally worth it.
Gavony Township - Proliferate!
Vault of the Archangel - Need to stay in the game a bit longer.
Boseiju, Who Shelters All - Screw your counterspell.

Phyresis was in there for a quick early kill with Serra Ascendant or with Atraxa, Praetors' Voice.

Both Brawn and Wonder are excellent ideas and I'd completely forgotten about Inkmoth Nexus

Phyresis seems weak, unless we look at some other options. Consider creatures with great abilities that would work with Phyresis and be great without it.

Here's something to consider, instead of Glorious Anthem effects what about more tools to make the deck more aggressive. Yes, +1/+1 for your creatures does help with the combat phase, but consider that you only need to attack for 10 points of 'damage'.
Here's some thing to look at:
Glory
Genesis
Brawn
Valor
Wonder
Fauna Shaman

True-Name Nemesis
Triskelion
Aven Mindcensor
Parallax Tide
Parallax Nexus
Gemstone Mine
Ash Barrens
Inkmoth Nexus
Reflecting Pool
Cascading Cataracts
Contagion Engine

Another attack vector:
Crucible of Worlds
Strip Mine
Exploration

Pretty expensive but worth it:
Prismatic Omen
Noble Hierarch
Bloom Tender
Mox Diamond
Survival of the Fittest

pokepower116 on Xantcha, Woke Agent

COL_Cashmoney I would say the list as currently built is not competitive at all. The deck is great for slower metas because it's dealing like 2-6 damage a turn pretty consistently so it puts a "clock" on the game. If the games only last 4-5 turns then it's not really doing much of anything. I guess it depends on what you mean by "competitive". If you're talking true cEDH like Prosh + Food Chain or Blood Pod; this deck won't ever really hold a candle up to those. If you mean more in lines of highly tuned 75% decks, I could see a chance of this deck being pretty decent.

Not sure how competitive this type of deck can be, but here are some suggestions if you wanted to make it more highly tuned:

Mana Crypt, Mana Vault, Grim Monolith, and Basalt Monolith - Fast mana is great at speeding up any deck. Basalt Monolith is definitely the weakest of the four, but I included it so that you can pair it with...

Rings of Brighthearth - Paired with Grim Monolith and Basalt Monolith lets you generate infinite colorless mana which you can use for Xantcha's activated ability. You can only take out one person this way before she comes back under your control and you have to sacrifice her, so cards like Ashnod's Altar, Phyrexian Altar, Phyrexian Tower, and Viscera Seer would be helpful inclusions if you want to go this route.

More draw & tutors to make the deck more consistent like Vampiric Tutor & Imperial Seal. I've never played with Ad Nauseam so I'm not sure how much I can recommend it; but after taking out all of the high CMC cards out of the deck I imagine it would be pretty great.

Also since this deck is pretty much an "aggro" deck, you can throw in cards like Phyresis or Tainted Strike to reduce the amount of damage you need to deal to take someone out. You could always try for one of those cards or a Grafted Exoskeleton onto Heartless Hidetsugu with a Glacial Chasm in play, but that's probably too slow.

Finally, cards that focus on resource denial like mass land destruction and discard can slow down the game so you have enough time to close it out like Blood Moon, Impending Disaster, Ruination, Stranglehold, Planar Void, Mindslicer, etc.

I think the best way to make this deck competitive is to throw in a bunch of stax elements that will disrupt your opponents' combos and slow the pace of the game down. This deck's current strategy wants to get some damaging permanents on the board and have them stick around for as long as possible. Kind of similar to a Brago lock, it doesn't matter how much damage you're doing a turn if your opponents can't respond to it. The difficult part of that though is finding enough stax cards to put in the deck (and drawing them consistently) and the sad fact that Xantcha's ability literally works to refill their hands. While Xantcha might be an interesting concept, you might have more luck making a more tuned version of Mogis, God of Slaughter since he helps with the resource denial plan too. I guess it just depends on whether you want an infinite mana sink or a card that actively helps keep your opponents' boards clear.

Let me know if this helps!
