With 3 colors, it will be harder for you to decide what to cut than it will to find means of dealing with big creatures. I suggest you start adding responses to you sideboard for starters, and after a bit of testing, you can work an appropriate number of copies into your mainboard. 31 is a lot of creatures. You can probably afford to cut up to 6 and still be pretty creature heavy.

With blue, you can 1) counterspell threats with budget stuff like Mana Leak , Essence Scatter , etc. You should try to choose such a spell on effectiveness and versatility. 2) bounce threats back to opponent's hands after they lose summoning sickness with things like Vapor Snag , or Void Snare . These options are easier to cheaper to cast, but aren't as permanent. Similar and more fun, there's stuff like Turn to Frog and Polymorphist's Jest which can be very effective after opponent's Declare Attackers phase. 3) Fight their creatures with stuff like Prey Upon . This option is great if you have a creature with deathtouch. 4) Destroy their creature (or anything else) with Beast Within . There's also Pongify , but that's less useful and more pricey. 5) Enchant their creatures into non-threats with stuff like Lignify or Imprisoned in the Moon .

There's also always Fog , which can set you up for lethal backswing and shouldn't be underestimated.

So you have a lot of options.

Killercrok that could be true. Though do you cast a land? At the moment I have removed Mesa Enchantress and Enchanted Evening . Both of them didn't do a whole lot and I found some new cards that interact a bit more in the deck. Including: Sephara, Sky's Blade and Polymorphist's Jest . The former making the faeries a bit more dangerous and the latter being a classic prank.

Hey, saw your forum topic asking for help.

Since you're a new player in Commander my advice is keep it simple. Build this deck around what your Commander does. Admiral Beckett Brass means Pirates and she doesn't do anything unless you have Pirates. Not Zombies, not Vampires or any other tribe, just Pirates.

The steal your opponents nonland permanents/creatures is a fine strategy, but don't go overboard with single cards that only give you a single steal effect on a single creature such as Act of Treason . Brass's combat damage to a player from three Pirates ability and Captivating Crew are repeatable ways to steal your opponents creatures/nonland permanents and that's better, really all you need for this effect.

There's only 27 lands here which is not enough land; you risk getting land screwed (not drawing or have lands on the battlefield). When this happens you're not able to play cards in your hand because you don't have lands on the battlefield. Getting land screwed is not fun and since you're a new player it's even worse as it can possibly make you not want to play again.

Getting land flooded (drawing too many lands/having too much land) is also not fun, but it's better to have lands to cast spells then to not have any lands at all. If land flooded you can at least cast Brass since she's in the Command Zone. All Commander deck builders have to clear deck space for enough lands.


My advice for the manabase is if you don't want to add other lands that you don't have then add more basic lands. Play a total of 38 lands with 15-20 basic lands, split up between Islands, Swamps and Mountains. Play more Islands than the rest, next is Swamps and last is Mountains. There's more blue and black Pirates/cards than red here. If you're willing to add lands you don't already have then I can help you on a budget to upgrade the manabase starting with Command Tower .

11 cards to consider cutting to add more lands:


Other cards to consider cutting to make 100 cards:

As far as cuts to consider, cut single cards that give a single effect such as stealing an opponent's creature for one turn. Only getting to cast a card once and only target one creature to steal for one turn is not good enough. Single card combat trick spells that can only target one creature are lackluster and can be cut. Auras that only help one creature and don't give evasion can also be cut. Ghostly Wings and Aqueous Form are fine since they can give Brass evasion making it easier for her to do combat damage to a player.

Simplify your deck's strategy, go with Pirates and cut the majority of the nonPirate creatures. Creatures such as Wonder , Nightveil Specter and Sower of Temptation are worth keeping especially Wonder. Specter and Sower are good cards to go with the theme of stealing your opponents cards. Clones are fine, but not high mana cost ones that can only copy a creature; honestly cut them.


Some redundancy (multiple cards that do the same effect or close to it) in Commander is good. But, if you're needing cuts then redundancy is a place to make cuts. Draw spells for instance are good redundancy such as Brainstorm , Night's Whisper , Read the Bones . These are all low mana cost/mana efficient draw spells. Opt and Sleight of Hand are also fine, but if you need cuts they can be cut. Draw spells such as Pirate's Pillage , Pirate's Prize , Train of Thought , Think Twice are not good, cut them. Low mana cost (0-2 CMC) mana rocks are more good redundancy: Sol Ring and Signets/Talismans. Chromatic Lantern and Commander's Sphere are much better than the other three drop mana rocks here; Mana Geode and Darksteel Ingot can be cut.

For your deck combat trick spells, counterspells and targeted creature removal is in my opinion bad redundancy. I'm not saying to not have these kinds of effects, but limit the amount of them you play. Counterspell for instance is a staple card of Commander play it, but Cancel , Sinister Sabotage and Rethink are worse then Counterspell, cut them. Sabotage is better than Cancel, etc.

Blasphemous Act and Fiery Cannonade is good redundancy. Murder is better than Doomblade, cut Doomblade. Sorcery or high mana cost instant creature removal can be cut such as Contract Killing and Price of Fame . Bitterblossom and Dreadhorde Invasion is good redundancy, but Bitterblossom is a much better card than Invasion. Invasion is a good card, but if you need to cut a card then cut it because you have Bitterblossom, otherwise keep it.

Spells that give all your creatures evasion of some type are fine, but don't go overboard with including lots of them because these cards do nothing without you controlling a creature; making them dead draws/dead cards in your hand too often. These kind of effects that can give all your creatures evasion are better if they can be repeatable or are a static ability such as Wonder or from an enchantment, not an aura. You want to play cards that can give your creatures lasting evasion more than a single card for a single effect on one turn.

I offer more advice if you would like. Good luck with your deck.

Pretty solid list, I'm always a fan of Curiosity combos too (as I'm sure you know). I'd probably play like Sudden Spoiling over Polymorphist's Jest and like Mystic Retrieval over Bond of Insight though.

You could also play something like Jace's Archivist to combo with your Narset, Parter of Veils , but I don't know how much of a monster you're trying to be.

Also other blue cards I like Cyclonic Rift and I love Echoing Truth it is great for a token sweeper and if you can pair it with Polymorphist's Jest you return all their creatures to hand. Also Swan Song is a nice spell and I would really suggest Isochron Scepter because you can cast counterspell over and over again. Underrated fun Eyes Everywhere trade and then play a return to hand card on it and you get it back and you get a scry but it is quite funny when you pull it off.

How do AEtherize , AEtherspouts and Polymorphist's Jest perform based on your expirience?

I've always been reluctant in putting them because on paper they look situational and/or limited to one opponent, prefering card such as Evacuation and Engulf the Shore that get (almost) every creature at any point.

Do you find that including them to preserve your side of the board is worth the "reststrictions"?

Hey my friend, really sweet deck. Can you tell us how does the deck perform in your meta ? Curve seems high vs aggro, especially without more mana dorks. But your control package can make this work. I'm looking for simic removals and I'd like to try Polymorphist's Jest . Is it good ? Sometimes a dead card ?

Cheers
