Rhadamanthus on Library of Leng and Sphinx …

Yes that's correct. Library of Leng's current Oracle text is a little more clear than the last printed version: If an effect causes you to discard a card, discard it, but you may put it on top of your library instead of into your graveyard. A cost is different from an effect, so the Library's replacement effect won't apply to the cost paid for the Sphinx's ability.

pyrophyte This was a deck that once ran Library of Leng. Perhaps I should consider it again. However, I generally don't employ Chains until I'm sure I'm going to be able to leverage it. There's an argument for being down to a single card per turn, but, theoretically, if I'm playing it correctly, I should be in a position to hold up a counterspell or removal while keeping everyone else to the same limit- which puts me ahead, if I'm dealing significant damage each turn, just for existing, regardless of being able to break parity. In that regard, it's a very similar philosophy to a well played Stasis. If you don't use it correctly, it can absolutely screw you, but, when done right, it can be back breaking for the rest of the table.

This is a great deck; love it! You've given me some ideas for my own Kozilek deck. Was wondering whether you've ever considered Library of Leng for this one, which works wonders when combined with Kozilek's countering ability because countering no longer makes you lose cards to the graveyard.

RiotRunner789 Heck yeah a tetsuko style deck with rats would be awesome. Rats sounds like a really fun tribal. I'm thinking of adding Supreme Will, and I'm thinking about switching it with Arcane Denial. I don't know what to switch out with Library of Leng.

Well, thinking of your mana leak theme,

Lose Focus is fun with replicate.

Supreme Will: Use to run this in standard to either protect or dig for your commander. Rat colony was a fun deck, just wish Tetsuko could be their commander. Confounding Riddle is just a newer version of this card as well (which you already run).

There are a few counters (2 or 3?) in recent sets that say something like, 'counter target spell unless opponent pays 2, get x small effect' Most I think cost 1U. Not sure if those would be your jam.

I think you have or are already running the best unlimited hand size cards. I will just reiterate Library of Leng. No discard phase = never discarding down no matter what you handsize is (negates something like Jin-Gitaxias, Core Augur being used against you).

Thanks a bunch, RiotRunner789! Very useful advice! I'm keeping Graceful Adept so that if it ever happens, I can make it use Prosthetic Injector. But Library of Leng doesn't affect the hand size does it? Like, what happens if I have more than 7 cards and skip my discard phase? Admiral's Order is great! Same with Dissipate and Unwind! However, I do enjoy cards that tie up mana the most. It's a win-win because if they choose not to pay the cost, they end up losing their card. And, if they can't that's also good. Not just that, but also if they do pay the cost, it makes it to where they can't spend much mana on anything else.

I'd swap Graceful Adept for Library of Leng. Cheaper, harder to remove, and added bonus against discard.

Cancel for any other counterspell. There are plenty of 1UU with upside such as personal favorite of mine, Admiral's Order. Rewind, Dissipate, Unwind and Negate are also solid budget options. Personally not a fan of Mana Leak-esk counters since if an opponent has a ton of Mana, they become useless. Also, Defense Grid is an odd choice for a blue deck since it hurts your own counters on your opponents turn.

I'd consider trying to find room for a card or cards like Coastal Piracy, Bident of Thassa, and The Indomitable.

Single protection to consider, Mithril Coat is amazing, Commander's Plate always pulls a ton of weight in mon color (may hurt commander's unblockable agaimst another monoblue but otherwise really helps), Dive Down not amazing, just a pet card when it was in standard.
