Sealock Monster
Creature — Octopus
Sealock Monster can't attack unless defending player controls an Island.
: Monstrosity 3. (If this creature isn't monstrous, put three +1/+1 counters on it and it becomes monstrous.)
When Sealock Monster becomes monstrous, target land becomes an Island in addition to its other types.

Personally i'd get rid of: Cloud Manta, Deep-Sea Terror, Deepglow Skate, Boundless Realms, Farseek, Genesis Storm, Nissa's Renewal, Skyshroud Claim, Giant Growth, Glissa's Scorn, Naturalize, Pulse of Murasa, Sweep Away
and replace with things like: Hedron Crab, Tidal Kraken, Serpent of the Endless Sea , Kraken of the Straits, Isleback Spawn, Grozoth, Sealock Monster, Stormsurge Kraken, Benthic Behemoth, Breaching Leviathan, Guard Gomazoa, Gomazoa, Dormant Gomazoa, Broken Bond

Octopus Umbra, Lorthos, the Tidemaker and Sealock Monster for flavor and some brute force.
Thada Adel, Acquisitor is about the best ramp mono blue has. So many Sol Rings...

Thassa's chosen: Arixmethes

Looks good, I just find that it feels very susceptible to early aggro, especially once you invest your mana in a big creature only to get it blown up by removal. I feel like you can include some thematic sea creatures like Chasm Skulker, Reef Worm, Sealock Monster, Sand Squid etc.

Despite the higher mana cost of Sealock Monster, it seems like it's going to work much better for you. In a four-player game, it's likely that someone will be playing blue--and thus have islands--but if not, you'll have a chance to gift somebody with their very own island when you use its monstrous ability. I see Sealock Monster fitting in here much better than Thing in the Ice Flip.

Thanks guys :)
And yes hydrothermia, the purpose of Nylea's Presence is to make an opponent's land an island for Sealock Monster and Harbor Serpent

Hi mushtard! I really like this deck list you have. I also have a Thassa, God of the Sea deck that looks almost like it! If I were to make some changes, I would take out any underwhelming cards like Thassa's Emissary & Sealock Monster for more impactful spells like Cyclonic Rift, Nykthos, Shrine to Nyx, & Pearl Lake Ancient. I'm also very unsure about the new Octopus Umbra. It's very flavorful, sure, but in a deck where your creatures are already big and scary it may not be that useful. I'll need to play with that more... If you ever want to take a look at my Thassa, God of the Sea deck and use it as a reference, you're more than welcome to do so anytime!
