Merfolk Secretkeeper

Merfolk Secretkeeper

Creature — Merfolk Wizard

(You may cast Merfolk Secretkeeper from exile if you sent it on an adventure.)

Venture Deeper

Sorcery — Adventure

Target player puts the top four cards of their library into their graveyard.

(You may cast Venture Deeper for from anywhere that you have the permission to cast this, then exile it on an adventure instead of putting it into your graveyard. When you have not chosen to cast Venture Deeper, this card is treated only as Merfolk Secretkeeper in whatever zone it is in.)

(Example scenarios for Venture Deeper: You may cast this off of Melek, Izzet Paragon. You may not target this with Snapcaster Mage. Thalia, Guardian of Thraben increases the cost of this. Electrodominance requires X=1. You may cast this from a cascade spell if the spell has a cost greater than Merfolk Secretkeeper's cost. If you cast a Venture Deeper that another player owns, only you may cast the Merfolk Secretkeeper that gets sent on an adventure, not the owner.)

Merfolk Secretkeeper Discussion

Mental Note, Merrow Witsniper, Merfolk Secretkeeper, Thought Scour, you name it. Sorry for the spam, just trying to help optimize the deck (even though my suggestions may not, in fact, help you do so because I don't necessarily know much about deckbuilding in this lane/whatever it is that I'm talking about)

What should I replace Merfolk Secretkeeper and Wall of Lost Thoughts??? I am planning on using these as chump blockers, but there could be better cards! I don't plan on old-fashioned milling to win, so their milling ability is useless to me unless I want to use Vantress Gargoyle early in the game.

Brineborn Cutthroat is a good card, but it usually shines in decks where everything in your deck can be played at instant speed, it wouldn't be bad in this deck, but it may not be exactly what you need.

Dimir Informant is very underwhelming, if you play it for the surveil you might as well run more Emry, Lurker of the Loch instead.

Merfolk Secretkeeper should be one of your go-to card, you could go up to 4 easily. In fact, you could also run Brazen Borrower 4 times for the control aspect, which means you could also run Lucky Clover, and that would give Emry, Lurker of the Loch something relevent to bring back, since I find your other artifact choice questionable. God-Pharaoh's Statue is situational and Wand of Vertebrae is better used in decks that can make use of their top-deck, like when playing Bolas's Citadel, it's not that great for self-milling.

Speaking of go-to cards, you need 4 Drowned Secrets. Also, Overwhelmed Apprentice is excellent for you and you should run 4 as well, especially if you run Thassa, Deep-Dwelling.

Persistent Petitioners is mediocre at best unless you have 4 advisors in play, and they're your only ones. Normally a deck that runs them will run way more of them, maybe like 20~30 of them since they get around the 4 limits per deck. There's nothing stopping you from running just 4, but they won't accomplish much.

Obviously Jace, Wielder of Mysteries is a must in this deck, but you may want to consider Ashiok, Dream Render too since he can mill 20 of your cards all by himself and still exiles your opponent's graveyard.

I don't think you run enough surveil to run Enhanced Surveillance, and Kiora Bests the Sea God seems out of place since it's usually a finisher in control decks while your plan is just to mill your library. It will rarely be the card you need to stay in control until you're done milling.

Dazzling Lights is pretty underwhelming too, easily something I would take out for any of the extra mentioned above.

Btw I don't mean to sound like "Your deck is all wrong!", it's always nice to see people trying to make decks themselves, it's way too easy to just copy the top meta decks.

Hopefully these suggestions will be helpful.

I really like this deck. Have you thought about Merfolk Secretkeeper? It might add a little more utility than Sweet Oblivion. You mill the same number of cards for one less mana, you get a body for one mana that will trigger your token makers, and you get to cast two blue spells total.

So, I built this on arena and it is so fun to play, especially when all the triggers go off! I added Narset, Parter of Veils for more card draw and Merfolk Secretkeeper for more mill triggers with Drowned Secrets.

Snowmen1 on Cauldron Reanimator

hey, thanks for the suggestions. Shriekhorn is definitely a faster mill spell than Minister of Inquiries, but I see a problem that it isn't a creature, which makes all of my mill spells less likely to make a turn 2 cauldron. I could see offsetting that by replacing Witch's Oven with another creature, but I think there's another way to build this deck.

The way I would look at the mill package for this deck is as a crabvine deck. It has no dredge cards because they don't further your strategy, and you cant utilize them for your game-plan if you just naturally draw them. Instead the deck wants cheap creatures that let you get out a vengevine ass early as turn 2. Similarly, we want a 1 mana mill spell that will also decrease the cost of a cauldron. having said that I'm looking at running Merfolk Secretkeeper because it fills a these slots better than both Shriekhorn and Minister of Inquiries in my opinion.

As for witch's oven, I would agree that it is probably too cute, but I think I would rather replace it with Gilded Goose, which is a creature, makes turn 2 emry possible, and it can help slow down the game.

I think that this deck is probably too awkward to build right, but there are a decent number of self mill options now, so it probably just comes down to testing to find the right one.

Nice unique take on Muldrotha! For starters, I would try to cut as many nonpermanents as possible because the less of those, the more cards you can cast with Muldrotha. I would take out Counterspell, Devious Cover-Up, and Price of Fame and replace them with cards like Lunar Force and Decree of Silence or even Siren Stormtamer and Kheru Spellsnatcher. You could also replace them with plain removal like Pernicious Deed, Oblivion Stone, Hostage Taker, etc. However, I very much like Spelljack because it is so on theme with the deck, keep it in! In terms of ramp, Cultivate and Explosive Vegetation are great choices, but you can get by with using Sakura-Tribe Elder, Wayfarer's Bauble, Khalni Heart Expedition, The Mending of Dominaria for your ramp package. These are useful because, once again, they are repeatable. I would also cut the Llanowar Elves if you add enough other ramp cards. Archaeomancer can be upgraded for Eternal Witness. Bond of Insight, Merfolk Secretkeeper, and Mire Triton feel a little out of place because they only mill a few cards. If you want big mill spells I would put in Mind Funeral and Traumatize and for permanents that mill, Sidisi, Brood Tyrant, Stitcher's Supplier, and Dreamborn Muse from your sideboard are all great cards and to top it all off Mesmeric Orb is a terrific card. If you want more instant and sorcery recurral The Mirari Conjecture is great for that. I'm not sure what Deadeye Navigator and Peregrine Drake are doing for you when they are on their own. Evil Twin, and any cards that copy other creatures are flavorful additions. Lastly, why not just steal their permanents when you can also steal their turns with Mindslaver. I hope my ideas have helped, and I hope you keep improving this deck!
