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

maybe Treasure Cruise is a nice addition to the deck: when you are totally screwed by only hitting lands or cards like Tome Scour, the deck fissles by not having enough cards with effect. With Treasure Cruise you can quickly add cards to your hand like Merfolk Secretkeeper so you get a good blocker and an additional mill opportunity

I'd also recomment some Stitcher's Supplier, because its not only a good miller, but it is also a really good blocker. the only negative thing is that it doesn't trigger your bird, so maybe not play for but two, or put some in the sideboard against swarm decks

It's a pretty good deck and I'm definitely gonna try it out! Keep the good work up! :)

I like the idea, High Tide seems a bit out of place as you will tend to play out your hand early. In it's place, something like Portal of Sanctuary could flicker your Venture Deeper into Merfolk Secretkeeper on each of your turns (multiples would also work).

I would want a bit of protection in the form of Turn Aside or Keep Safe. A fourth Snap would usually be stronger than one Lotus Petal.

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.
