Brineborn Cutthroat Discussion

TheVectornaut on Blue/Black Beginner Deck

I think this deck is really well-positioned to become a "draw-go" style control deck that plays instants and flash creatures on others' turns. Pteramander , Augur of Bolas , Brineborn Cutthroat , Threnody Singer , Vodalian Arcanist , Naiad of Hidden Coves , Wavebreak Hippocamp , Murmuring Mystic , and all of your instants (save for the likely too slow 4 mana ones) already fit in such an archetype to at least some extent. The horse fish is particularly insane as a card draw engine, and I'd try to get a playset of it if you can. Stacking them to draw even more cards with Nymris, Oona's Trickster , Baral, Chief of Compliance , Slitherwisp , etc. would also make Ominous Seas more viable, possibly even supplemented by draw payoffs like Chasm Skulker and Nadir Kraken .

Some other options that care about flash might be Cunning Nightbonder , Teferi, Mage of Zhalfir , Leyline of Anticipation , Torrential Gearhulk , and Mystical Teachings .

For more generally good instants, Counterspell , Mana Leak , Countersquall , Frantic Search , AEtherize , Vapor Snag , Rewind , Cryptic Command , Opt , and Brainstorm (if you're playing with the legacy banned list) are options of varying budgets and power levels for a control deck.

The first cards I'd cut would be anything with suspend or that applies keyword ability counters. I think some amount of counter manipulation would be needed to maximize the value from such cards (with Clockspinning , Jhoira's Timebug , Paradox Haze , and Nikara, Lair Scavenger being a few things that come to mind). Then, I'd cull any sorceries or creatures that would take up all your mana on your own turn for minimal impact. Dead Revels , Frost Lynx , Alirios, Enraptured , and so on.

Sorry it took me a while to submit this after seeing the deck get posted earlier this week. Let me know if you have any questions and good luck with your build!

My knowledge of budget cards is quite limited but here are some suggestions:
Flame Slash over Lava Coil in the sideboard
Also I'd go up to 16 Creatures with either Pteramander or Brineborn Cutthroat

I wonder about the adapt card, too. I actually dropped adapt out of my Simic deck, but since you don't have most of the cards, I'm thinking about putting it as the primary mechanic in that one, or switching to elemental tribal.

You might try Brineborn Cutthroat or Goblin Electromancer if you have one.

I think Deeproot Waters is must in any Merfolk deck:D and Deeproot Elite and Metallic Mimic help you put counters on your merfolks. i also think Mowu is not really great card for this deck since kumena puts counters only on mefloks...And i would cut Brineborn Cutthroat as well, hes great for control decks with loooots of interactions but i think you can find much better fit since you are playing only 14 instants and very few flash spells. If you are interested you can check my profile....i started brewing merfolks too....deck is nowhere near finished.... i basicaly throw every merfolk and triball spell i could find together..so you can check your options there...i also have deck centered around +1+1counter shenenigans if you are interested in upgrading that way instead of tribal. Good luck with your deck!:)

While I hate playing against counter-heavy decks, and probably shouldn't help them improve, I do have some ways to (hopefully) make the deck better:

  • If you're going to play any of the eternal formats, I think Ice-Fang Coatl over Ambush Viper and play snow lands is better, if you want an instant-speed deathtoucher.

  • As is, you're running too few lands, given the amount of 4-drops. Also, I'd play some amount of Rewind, as it lets you counter a spell AND play a threat on turn 4+.

  • Brazen Borrower is probably the best interaction this deck has access to and it's definitely a stronger card than Faerie Duelist. Unless you're going for a budget deck.

  • From my experience, Brineborn Cutthroat is better than Wildborn Preserver. You're not always sitting on mana to pump the Preserver and they get worse in multiples. Cutthroat doesn't.

  • Sea-Dasher Octopus could be nice in some amount, as it can start drawing extra cards as soon as turn 2 off of a turn 1 Spectral Sailor.

  • Titanic Growth is underwhelming in flash decks. They just need to tempo out the opponent, which is best done with value creatures and bounce and/or counter spells.

  • Frilled Mystic is a great tempo play. If you up the land count, you should play all 4.

Hope that helps. Good luck with the deck!

I've considered running Blackguard, but I am perfectly ok with them targeting using removal on Enforcer, as she is just in there because of her synergy with Brazen Borrower and Brineborn Cutthroat as well as contributing to the flash aspect of the deck.

You should consider 4x Spectral Sailor - they're absolutely nuts with the Octopus and the other mutaters, they're cheap ways to trigger Brineborn Cutthroat, and the 4-mana ability means you can always choose between drawing, playing a creature, or countering.

I think they're much better than Lochmere Serpent and probably the two Greatshark, or perhaps two Pouncing Shoreshark.

Also, I'm surprised to see no Slitherwisp?

Finally, 1-2 Castle Vantress might be a nice addition.

Creature (26) I'd go:

4xBrazen Borrower; 4xBrineborn Cutthroat; 4xCunning Nightbonder; 4xLochmere Serpent; 4xSea-Dasher Octopus; 4xSlitherwisp; 2xThryx, the Sudden Storm;

But that is just my play style. I like your deck.
