Psychosis Crawler doesn't die, The game checks toughness before and after the spell so it wouldn't be dead. Psychic Spiral sounds fun but it hits only one player. I'm thinking I'm playing in a big group like 4 other players I should put Laboratory Maniac in because that could be a lot of cards drawn. Cerebral Vortex sounds good a warrants testing haven't gotten around to it. The problem being it's kid of dead and not resistant to counter magic. Though by the time you cast it you should have gotten past them.

Love the idea of trying to make Nekusar competitive, and this is a very well constructed deck. I also run a Nekusar commander deck, and while it is tuned, it will probably never hit competitive level. Nonetheless, there are a couple ideas/suggestions I would like you to consider.

First off, as of this comment, I noticed the deck is running 2 cards short of 100. That should be the first thing to change, unless there are cards not listed yet because you're play testing. If so, then ignore this.

Second, being built around Nekusar, this deck looks rather fragile. I would suggest some more counter magic. Arcane Denial is a strong Counterspell considering it replaces itself. Sure the opponent can draw 2 cards but it's a small price to pay for protecting your win con, or stopping another's. I see you have Fork and the like, and since they can copy spells, they can be used as cheap counters, but I would recommend at least switching out Increasing Vengeance as it is limited to only copying your spells (however, since it can copy twice with a flashback, Reiterate would be my second choice as it is more expensive, even considering the buyback option).

While Liliana's Caress and Megrim are great alternatives to dwindle your opponents' life totals, I would recommend replacing Megrim with Bloodchief Ascension . I realize speed is everything, and getting the quest counters takes time, but it does cost 2 mana cheaper allowing you to maximize your spell-slinging. With Nekusar on the field, you're likely to get the counters before your next turn.

Shattering Spree is an amazing card, but depending on how relevant artifacts are in your meta, Vandalblast might work as an alternative (take this with a grain of salt: I realize the former can cost less mana but the latter is more splashable; hence why it depends on relevancy). I'd also recommend some control/removal such as Cyclonic Rift and possibly Toxic Deluge .

Some lands I recommend (other than the expensive alpha dual-lands) are Riptide Laboratory to rescue your commander or reuse Snapcaster Mage and Cavern of Souls to make him uncounterable (that is, if counter magic is relevant in your meta). I would recommend swapping out Gemstone Mine for one of these.

Personally, I'm not a fan of Helm of Awakening for benefiting everyone's spells or a couple of your extra mana sources (Charcoal Diamond , Inner Fire , Lotus Petal , Pentad Prism , Simian Spirit Guide ) for their limited use (or, in the case for Inner Fire , being a sorcery), but if they work for you by all means, keep them.

Obviously you get final say for your deck (and I know I suggested very little for such a rant), but I highly recommend play testing these suggestions (or finding cards better suited to replace the ones I don't believe do the deck justice) and see how you like them for your deck. It might add some balance to your glass cannon, yet it could also make the deck slower/weaker. Either way, great deck thus far and a +1 from me. Let me know how these play out if you do test them.

A final thought: I am assuming Mana Drain and Timetwister are out of the budget, but if not, I would suggest those as well.

How is Forced Fruition not in here? its not even mentioned. last time i built a neksar deck that card rocked

I play with Weirdhat IRL on a fairly regular basis, so I'll answer some of the questions.Counter magic was kept low because of how little he needs, on force or pact let's him win. The 2 cmc counterspells aren't that great for this deck, Dispel or Spell Pierce would help more. Forced Fruition is far too slow and blue mana intensive for him to bother with. Timetwister was on his list to get.

The cmc for Forced Fruition is to high and the card itself is a more reactive card than proactive. It has to wait for someone to cast a spell before it does something. Timetwister is definitely going in the deck it is a matter of when. The cards that I can see replacing are Fate Unraveler , and Psychosis Crawler . what Should take their place?I am not sure. the problem isn't that they don't pull their weight on the field it's getting them there that's the hard part.

Thanks ShikiTen the missing cards were Jet Medallion , Ruby Medallion , and Sapphire Medallion .

How are the medallions working out? At first glance they seemed too situational, so I didn't include them in my list. Also, I'm still defending either Mind Over Matter or Dream Halls for you swaps for Psychosis Crawler since you mentioned cutting him. I'm also still an advocate of the infect cards too. Suggestions?

Maybe some added deck fixing is in order. Lim-Dul's Vault and Sensei's Divining Top . Both are cheap in mana cost and very effective.

Standstill might also be worth testing out. If played before you wheel, the damage potential is worth noting. Also cheap to cast.

Standstill seems very strong. Plays along the lines of lions eye diamond in this deck. I've thought of adding lim dul's vault myself... Literally about 3 hours ago, and top is never bad...?!!?!!?

Also if you take out fate unraveler and psychosis crawler, your auras get a lot a worse... Just something to think about.

I noticed your no longer playing the diamonds and are now playing the medallions. How's that working out for you? I threw the medallions in the other day but have yet to actually draw one.

Deciding between medallions and diamonds is kind of difficult the diamonds are relevant early early game when what you want is to tap for mana, but any other time they Are completely dead while the medallions are not all that great early game but pretty awesome when you start sneaking them in while storming out. The infect cards are great but distracting. They do damage in a different direction and I have several times tricked myself into pulling the trigger in them. I think the card slots they take up are better used by other cards. I had cards like Lim-Dul's Vault in this deck early on and they slowed down the deck and took up cards slots better used by other cards. I'm not a fan of Standstill haven't tested it but I don't fancy waiting around for someone or myself to make a move and I don't want to give my opponents card advantage even with my general out.

You have a point about less pain creatures weakening my auras, but I don't think backing it up with more pain creatures in the deck is worth it. Nekusar is enough And if he dies I can still deal with it (hopefully)

In my play group, Nekusar loves to die... They hate him, so I like at least one way to still deal damage when Nekusar gets tucked. I noticed that digging for caress and megrim just didn't do as much as I needed.

Megrim , Liliana's Caress , and Waste Not have performed exceptionally when I've drawn them, mostly because they are so cheap and get so much done. alot of the time nekusar has just been bait and I drop them immediately after. Sometimes going off without anything on the field is viable especially with Tendrils of Agony hiding in the deck. Adding Psychosis Crawler is certain if Cyclonic Rift under performs. Cyclonic Rift is a reactive card.

This is true but crawler is way too much mana for me to want to cast him and tendrils only kills one player outright, leaving me with 2 players left. I forgot about waste not because every time I've casted it, it get destroyed before I get any use out of it.

Tendrils+snappy kills 2 and god forbid he adds brain freeze and just storms out the table.

I don't like Brain Freeze because if the player has eldrazi I'm smoked. I think having one storm card is best. If I were to add a second it would probably be Mind's Desire . the key to to landing a threat and using it is to play as many as quickly as possible. The cmc for Psychosis Crawler is one of the reasons I don't like it that much Fate Unraveler is also a possibility but its abilities aren't as powerful.

I was looking at another nekusar deck and saw Thoughts of Ruin and Decree of Annihilation , looks great for hosing decks with land based mana and cycling can't be countered.

Why not try a burning/cunning wishboard? The LD spells seem out of place, why nuke lands when you can win? I thin it's Gona be a dead draw more then not(plus I love wish spells).

Problem is this card slot should really be going to Timetwister , but at the moment it's whatever I feel like testing.

Try one of the wishes burning/cunning are the two best ones honestly, you can get an emergency counterspell, a wipe or another reactive spell or keep a few spells based around your game plan.

I will look into it, probably start building a sideboard anyway

My sideboard is looking like just 1v1 switches. But I can't wait to see it.

I remember seeing Prismatic Lens that could be a could 99th slot
