Library of Leng Discussion

DaringApprentice on Part-ners: Ravos, SoulCycler

This looks like a lot of fun, great to see these blasts from the past get used! One card that you might consider for ramp is Thran Turbine, could give you a free cycle each turn. As for lower CMC creatures, some that I think could be useful are Cryptbreaker, Stoic Champion, Ruthless Sniper, Cho-Arrim Alchemist, Pack Rat, Skirk Ridge Exhumer, Undertaker, and Devout Witness, since they get a different kind of value out of discards than cycling. Similarly, Key to the City and Smuggler's Copter can allow you to use discards for different kinds of value.

As far as other cards related to cycling go, did you consider Ash Barrens, Gilded Light, Stir the Sands, Unearth, Radiant's Judgment, Street Wraith, Viscera Dragger, and Pitiless Vizier? I'm not sure if those fit in perfectly, but they might be worth considering.

If you wanted to make all players discard but have you benefit more from it, you might consider cards like Oppression and Necrogen Mists. I also think Library of Leng is worth looking at, but it might not fit your strategy.

Do you think getting Hellbent is something you are looking to do with this deck? If the former, maybe something like Gibbering Descent, Asylum Visitor, Dark Suspicions, Grim Strider, or Hollowborn Barghest could be interesting. In either case, some card draw like Phyrexian Arena could be very useful.

Also, watch out for Stabilizer!

Oh, I forgot to mention Overwhelming Denial and Last Word, they can't be Baral'd. I think Library of Leng is better than the Academy land, and Ludevic's Test Subject  Flip to dump your counterspell mana.

Given that you normally only have Nekusar around for a single turn on a good day, I have always stayed away from too many permanent that without him or similar effect, they turn against you. Forced Fruition is one of the worst offenders in my opinion. Without pain, you are allowing people to see their entire deck, when you are already wheeling them too. It does enable mill victory, but I'd be afraid of them getting more cards for free.

A few suggestions I can make:

Library of Leng - makes all wheels optional for you, plus incite hand size for one mana? Too good.

Sigil of Sleep - on Nekusar it turns him into Cyclonic Rift with a wheel.

Helm of the Ghastlord - this is a less popular card due to being an aura at 4 that won't win the game. However, this transforms Nekusar into Leovold, Emissary of Trest. You get to play a banned card, more or less.

Get rid of Day's Undoing. Unless you can cast it NOT on your turn, that last phrase will remove Nekusar's damage from the stack. Trade it for a Time Reversal or one of its more expensive cousins.

That's what I got for now! Super hard to critique on a small phone

Greater Good + Library of Leng (if you have space), but Greater Good for sure.

League I'm in is constantly dominated by an Omnath deck that runs lots of low CMC, early game ramps to get as much mana as possible to make Omnath as big as possible. Plop down Greater Good, sac Omnath to it, draw 10+, discard 3, play Omnath again, sac again, draw 6~, discard 3, and end with a net total of 10 extra cards that turn. Usually several of them cost less than the 5 mana left and play his hand and win next turn with a 30~/30~ omnath with Rancor and stupid stuff.

Despite running a far higher CMC deck than he is, you have plenty of fatties to draw from if they ever get targeted or if you just need the draw.

I'd cut Kavu Titan or Sylvan Advocate. They have the least synergy with the rest of your deck.

I wouldn't look at the discard effect as a downside... I would try to take advantage of it.

Swap in a few madness cards maybe something like Fiery Temper or Avacyn's Judgment can replace some of the burn or kill spells you have now. You can also run some re-animator cards like Phyrexian Reclamation, Patriarch's Bidding could be really strong for you here as well. There are plenty of ways for you to take advantage of the discard clause.

Also Library of Leng is a very overlooked card in commander that allows you to discard cards to the top of your library. I think it works wonders with Cow Commander 2.0 (Tahngarth, Talruum Hero is 1.0).

I am looking to build this guy too. can't have too many ideas!

  1. Spellbook --> Library of Leng
  2. Swamp --> Coastal Piracy
  3. Island --> Rogue's Passage

LeaPlath, I keep a lot of small unblockable creatures so I can Ninjutsu without worry. I have use equipment or enchantments to make them unblockable so I'm able to trigger their abilities with ease.

Bulletproofcats on [Primer] Nightmare by Design

Vasseer Thank you again for reading through my explanations. Now as for you suggestions, everything but Chittering Rats has been in the deck at some point.

Nether Traitor's body is irrelevant as he won't be around to block or attack. Is ran Reassembling Skeleton over him for awhile and since I always have a creature dying Traitor is cheaper to bring back.

Dictate of Erebos was also in the deck along with Butcher of Malakir. Decided I didn't need all that.

Library of Leng is there as a just incase. If I have Necro out and need my cards it allows me to put them into my hand and not exile the rest. and I don't need Chainer to waste mana keeping a creature. Don't want to replace the lands I already have.

Mindcrank over anything else because it doesn't require anything after its cast. I don't need to dump mana into Chainer into it. I have Mindslicer for that.

Dark Depths is a card i have never really liked, plus 30 mana is better used else where.

Despise will be switched out for Thoughtseize I was using it in another deck and slipped my mind on putting it back it.

Night's Whisper will probably find its way in as I want to run both.

Darkness being able to tutor for it and cast in response to being dealt lethal has saved me quite a few times.

Rune-Scarred Demon ran for a long time. decided I had enough tutor effects. I do side board it though.

Infernal Darkness I figured I have the tutors to pull and stick Contamination I don't need a second one.

Skullclamp was omitted because of Necro, I have it side boarded though.

Laquatus's Champion I decided against this as that is really mana intense and its a dead card IMO if I draw it.

All in all you are right that Chainer isn't that best at all. I liked that challenge of it. Also never played the deck 1v1 as I know Ill be murdered. But I don't mean to come off rude! I am always playing this deck and all your suggestions are in the side board. They will be rotated in and possibly permeant as the deck evolves! Thank you again! and happy deck building
