Weekly Sale Commander: From the Depths - Sea Monsters!

Posted on July 24, 2025

Hi folks! Welcome to the Weekly Sale Column! This column will be aimed at showing you some cards on sale that could give you some new ideas for your lists. They will *usually* be Commander lists in Bracket 3 as well so you'll be able to play these in any Bracket 3 (or higher) pods. If you want to play in lower pods, just swap out the Game Changers for other choices and/or add more along with some other competitive combos if you want to compete with Bracket 4 and 5 pods! Remember that the weekly sale ends on Sunday night at 11:59 PM EST, so you have until then to get your cards ordered!

Today, we bring you a Commander list from this week's From the Depths Sale, featuring all of the various Sea Monsters! Some of Magic's finest denizens of the deep have graced this sale, including a whole host of Krakens, Leviathans, Serpents, and Octopuses (yes, it is Octopuses, not Octopi). If you want to explore the other side of the sale, check out this week's earlier list, featuring Merfolk!

Merfolk are so Versatile!

Speaking of Merfolk, leading this group of monsters is actually another Merfolk! Kiora, Sovereign of the Deep is a 5-drop Simic 4/5 with Vigilance and Ward 3 (she protects herself well!) with a delightful triggered ability. Whenever you cast a Kraken, Leviathan, Octopus, or Serpent (aka a Sea Monster) from your hand, you get to look at the top cards of your deck equal to its mana value. You then get to cast any free spell from those cards, as long as it costs less than the aforementioned Sea Monster! Free spells are back!

There were a few other options for a commander in this list that were actual Sea Monsters, like Arixmethes, Slumbering Isle, Aesi, Tyrant of Gyre Strait, either of the Komas, or Sin, Unending Cataclysm, but I wanted our commander to be better costed because this deck has a lot of expensive spells. Kiora was the logical choice here, and our Sea Monsters can focus on destruction instead of leading. Lets get into our Monsters!

Release the Kraken! (or the Octopus)

Davy Jones' goodest boy from the seas is the first of our four Sea Monster types! We're going to include Octopuses here, because we don't have too many and they're quite similar. If you wanna know the difference, one ravages the Black Pearl while trying to take down a man, the other one gets turned into Takoyaki and is real (tasty). As far as cards go, we have a few earlier options that help give us some utility, card draw, and ramp, in the form of Nadir Kraken, Arixmethes, Slumbering Isle, Monstrosity of the Lake, Stormsurge Kraken, and Sea-Dasher Octopus. Having earlier options is huge in this deck, as you'll soon find out from our other big baddies.

Speaking of, the Watcher in the Water (Middle Earth's Kraken) and Spawning Kraken help flood our board with more denizens of the deep. Scourge of Fleets and Tromokratis help clear our opponents' creatures, either by bouncing them or eating them. Lorthos, the Tidemaker, our lone large Octopus, spends 8 mana to sleep 8 permanents, which can basically lock someone down if you can keep attacking and paying. Deep-Sea Kraken gives the same nine-turn eerie feeling that The Watcher in the Water gives, while starting that creepy music on turn three when you can suspend it. All of these cephalopods further our goal of drowning our opponents!

My Anaconda Don't, My Anaconda Don't

Next up, we have Serpents! All of these Serpents all cost either 6 or 7, so we don't play too many of them, but they all fill a great slot of either a good beatstick for your opponents or some utility. Both of the Komas, (Cosmos Serpent and World-Eater) both create 3/3 tokens that Cosmos Serpent can use to arrest permanents for a turn or make itself indestructible. Aesi, Tyrant of Gyre Strait gives us some card draw and late game ramp and Xolatoyac floods lands into Islands while also untapping anything you control with a counter (which can include your flooded lands!) at your end step. Benthic Anomaly creates creepy combined copies of your opponents creatures and Serpent of Yawning Depths makes all of our friends unblockable to anything that isn't another Sea Monster!

Groudon Could Never Compete with Kyogre

As a giant Pokemon fan, I'm on the side of Kyogre in the Groudon vs. Kyogre debate, which is nice here, because Kyogre is actually based on our final Sea Monster, Leviathan! Starting off from Final Fantasy, we have Sin, Unending Cataclysm and Summon: Leviathan (I know, shocker, it's a Leviathan). Sin is able to remove all counters from your choice of artifacts, creatures, and enchantments, and turn those into twice as many +1/+1's. When it dies, it moves those onto something else you control, and then gets recycled into the deck.

Summon: Leviathan, and also Slinn Voda, the Rising Deep, return all but Sea Monsters to their owners hand. These two also leave Merfolk in play, which is great for Kiora! Famished Worldsire, courtesy of Edge of Eternities, turns your lands into both +1/+1 counters and potentially more lands. If you play Lumra, Bellow of the Woods, just put in Famished Worldsire and don't ask any questions, trust me. Breaching Leviathan taps non-Blue creatures and the dynamic duo of Inkwell Leviathan and Simic Sky Swallower evade their way into your opponents' life totals.

The Calm Before the Storm

We'll need ways to actually cast these cards. We get the convenience of being a Green deck, so we get to ramp to our heart's content and we've included a lot. From Farseek to Hour of Promise, we've included quite a bit of land search to help us cast our larger spells earlier. It's not even too bad if we run out of steam with Kiora, as long as we have one Sea Monster to trigger her, since she digs down for more cards.

We've also included a few enchantments for card draw. I figured Up the Beanstalk didn't make enough of a 60-card constructed fuss, so I've included that here, along with Garruk's Uprising and Kozilek's Unsealing. Quest for Ula's Temple and Monstrous Vortex lead to more free cards, so we'll definitely include those. Finally, to round out, we've added Last March of the Ents, as a big flood-the-board option for the late game along with Monster Manual, Quicksilver Amulet, and Elvish Piper for some more Sea Monster cheating!

Our Game Changers that we've included are Wordly Tutor, Fierce Guardianship, and Force of Will! Fierce and Force are great in a deck where we're likely tapping out, because we'll need interaction while still keeping our plan going. Tutor helps us find whichever Sea Monster that we want, or even helps us get Eternal Witness to bring a specific baddie back from the graveyard! If you want to swap those out, I personally like any good free spell interaction, like Force of Vigor, Commandeer, or Subtlety/Endurance, and Worldly Tutor can just come out for any pet spell or card you want to play (I'm partial to Seedtime or Summoning Trap).

If you're looking to beef this up for Bracket 4 or 5, Hullbreaker Horror combos with Sol Ring for infinite colorless mana and Freed from the Real/Pemmin's Aura combo with Arixmethes for infinite Green mana, and then you can just cast as many cards as you can until you run out of steam!

Here's the list below, thanks for reading. See you next week!
