Ah man! Beware the counterspells O.O a single Hinder and you are so dead. You have a strong suit of french banlist legal accelators and discard, so important. I can suggest you a couple of other Infect dudes, you know... just in case. If you want, Nightmare Lash is a good second lash. ;) You can look at my Skittle deck, even if it's made for small multiplayer pod, it can gives you some ideas.

Luckily for our side, Duel Commander rules designate that if Commanders were to be tucked via something like Hinder you can opt to put them in the command zone. B)

My stance on additional infect creatures is kinda mixed. The only ones that don't have entirely terrible stats are Plague Stinger , Phyrexian Crusader , Blightsteel Colossus and Phyrexian Vatmother , and as a deck that doesnt have a single Bribery target it would take a considerable argument to sway me at this point, not to mention the hit on other slots of discard, card advantage and the sort that would have to be cut to allocate the changes (They need them some equipments too remember (: )

I used to also run Nightmare Lash , but I found that I would draw both of them (Lashwrithe ) too much. I like the option to pay mana instead of life atm, because with the fetches and things like Snuff Out and Phyrexian Arena , I tend to go through life at a reasonable pace, and would like to conserve when I can for Unspeakable Symbol .

I Like your multiplayer list btw, +1 from me (:

I got a Skithiryx deck too, u should definitely put a lethal vapors in this deck. I got pretty much all the board removals if you need more to find out more cards to put in for this deck.

Lethal Vapors and Ashes to Ashes

As far as I've read, you can only put commanders in the zone as a replacement effect for graveyard or exile. A hinder, or a condemn, will in fact bottom your commander. Of course with your tutoring, I don't really see it as a death sentence.

As stated in the Duel Commander rules page http://duelcommander.com/rules/:

"Second, in addition to the ability to put the Commander back into the Command Zone if it would go to the graveyard or be exiled, you may do so also if it would be put into your library."

The second part is crucial here. In an instance of something like Condemn (Hinder works similarly mechanically here), when the spell resolves, it places your commander into your library (the key is from -anywhere-). You then get the choice to return your Commander back into the Command Zone, similarly to the replacement effects from exile or dying (:

((I might have to edit the deckname to help clarify to people during deckcycles or whatever))

this can come and save you at some point Withering Boon

Ugh I know. I REALLY like Withering Boon . It was in the deck for a while. I just found it was. Too high variance? Like, if you're trying to find a topdeckable out to something it's just a dead draw. And there's other problems with it sometimes as well. It's in the Maybeboard, but it's hard to find a slot to put it in that I really like.

Slaughter Pact and Necrologia seem like a good add imo

The thing I don't like about Slaughter Pact is it's directly competing with Snuff Out . Both effectively cost zero with drawbacks. In the early game I prefer Snuff Out because I'm not choked for mana on the next turn, and can be put in a vulnerable position with getting Wasteland ed or Dust Bowl 'd for a free win. They both hit the same targets, but Snuff Out also buries instead of destroys, which is only relevant maybe 0.05% of the time, but if you keep it in mind it's pretty feel bad.

Necrologia Seems pretty fun to try out, but I don't really see it as a long term inclusion. I don't play it for the same reason I don't play Hatred : The additional cost. There's a lot of ways to swing in for the win with skithiryx that don't leave you vulnerable to counters. Hell, sometimes against certain decks it's more effective to play the long game, which is what Caress of Phyrexia is for. As a 'big draw' spell, you might as well play Skeletal Scrying ; same effect, can go bigger, and results in a weaker loss of resources if it's disrupted.

(Lost of control heavy decks in my meta; it's not the catch all rule of thumb with Hatred effects, but I feel strongly that given the comp it's the right call)

I am personally a huge fan of running a few evasive infect creatures, namely Phyrexian Crusader and Plague Stinger as additional wincons in Skittles. It allows you to win games when your general gets hit by Nevermore or other enchantments that keep it from doing anything, and offers more versatility than just the Inkmoth nexus.

I like them, particularly crusader. I think he's got alright stats and his evasion is relevant in some matchups.I wish he could do something else than just swing for damage though, he doesn't have a lot of spell utility, something I evaluate pretty highly when it comes to creatures (Maybe something like Whispering Specter?).

Nevermore is a moderately problematic permanent, but not as bad as say something like Ensnaring Bridge for example, which aside from using nexus is actually unbeatable. Nevermore on the other hand can be dealt with by things like All Is Dust and Dystopia, the latter doing a surprisingly good job of that in fact. I'd probably rate Nevermore and similar things to a Maze of Ith, a setback but something beatable. If these things cause more issues maybe ill look to retooling the deck towards more artifact and enchantment inclusive sweepers.
