9-lives on Void Shatter's Thousand Virulent Cuts

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.

Cataclysm can work against you based on opponents' picks and though Enter the Infinite is impressive & works with Omniscience, I don't see Thassa's Oracle or Laboratory Maniac, nor do I see Grapeshot. Consider instead Boros Charm + Armageddon which most people will hate & sometimes outright scoop after.

Mana Vault is more of a risk than you might think without untap mechanics (See Derevi, last paragraph). Consider Thought Vessel or even Library of Leng.

Replace Lion's Eye Diamond with Land Tax. The latter also helps offset the pain from Need for Speed, which is a cool find.

Consider Smothering Tithe instead of Mystic Remora: Remora usually only nets a few cards at beginning, and will often slow you down more than it helps. The former performs MUCH more consistently, and will net you more mana to focus on spells and counters.

Concerning your SB: If you want to go maximum lock-stax, I'd recommend Derevi, Empyrial Tactician. Use Winter Orb, Static Orb & Stasis, use Kismet and Loxodon Gatekeeper, maybe even Elesh Norn, Mother of Machines. Use fetches + basic lands, huge ramp, and Back to Basics just to spite opponents. NB: Mana Vault smacks with Derevi.

Library of Leng will keep you from discarding your extra cards and combos with Putrid Imp. Discard your highest CMC card to the top of your library and keep hitting people for max damage every round.

Spark Double can copy Yuriko so you get 2 card draws for each ninja.

Pilgrim's Eye gives you a land ETB, has flying so you can usually attack with it, then recast for 3 mana after you Ninjitsu

The Cauldron of Eternity, Curse of the Cabal and Needlebite Trap have a high CMC but you can also cast them cheap

I would suggest you run Library of Leng in the deck, which would allow yo to loop your Commander a lot faster.

K34 on Library of Leng/ Magus of …

If I have Library of Leng and Magus of the Future in play together, am I able to just repeatedly cast non-permanent spells? If they work how I think they do, I could just cast Reach Through Mists and Peek alternating for as long as I have available blue mana. Or perhaps I'm misunderstanding discard as a function on Leng?

Swebb87 on library of Leng cost Vs …

Hi, the rules text of Library of Leng on MTG say that if the discard is part of a cost you can't use the ability of Leng, only when it's an effect being applied to you. So does this mean Queen Kayla bin-Kroog works as the cost is 4 and tap. Whereas Gix, Yawgmoth Praetor wouldn't work as discarding cards is part of the costs of his ability?

Thanks
