Thassa, God of the Sea

Legendary Enchantment Creature — God


As long as your devotion to blue is less than five, Thassa isn't a creature. (Each in the mana costs of permanents you control adds to your devotion to blue.)

At the beginning of your upkeep, scry 1.

: Target creature you control can't be blocked this turn.

Thassa, God of the Sea Discussion

MoJoMiXuP on Creatures or instant/sorcery? Tromokratis voltron

I second Runechanter's Pike and would add Grafted Exoskeleton to that as well. Also, given that you are mono colored and have mostly basics, I'd shave one for Rogue's Passage. Thassa, God of the Sea is another awesome card to help push damage through, among other things.

Looking at your list, I'd generally suggest cutting down on creatures/artifacts/enchantments and the like in order to keep your instant/sorcery count high as these spell types are where blue's advantage lies.

To give you some ideas, here's a voltron big blue brew I've been working on, though it is a different commander...Ocean chomp

I like Thassa, God of the Sea but i doubt you'll be able to get your devotion high enough so i would think if you wanted that affect Aqueous Form might be better

Personally i wouldn't run it in mine but i do have more bounce and removal so it might be needed to sneak in damage!!!

Also what do you think about Thassa, God of the Sea? Scrying every turn can add up a lot of value, and being able to make a 6/5 or 7/8 unblockable can also help close out games.

Hey, DrkNinja. I'm writing in response to your request posted on the Ad your CMD deck. First of all, I like your choice of general. Options for EDH Merfolk have been neglected for a long time and finally, now we have good choices. I've a competitive mindset towards edh but after reading some of the comments, I think you're not trying to make a super competitive list. That's fine. I'll try helping you making cuts, so that you have slots for new cards. Let's talk about cards that I'd make good additions to the deck and then the ones that you could remove from the present list.

If Gaea's Cradle is out of question, I second Suns_Champion's suggestion to include Growing Rites of Itlimoc  Flip. Your deck seems largely a merfolk-based deck, which makes sense given your commander. Cradle/Rites take advantage of that to make degenerate mana and set up turns in which you can make big plays (game-winning plays or just casting fun but mana-intensive spells). I also agree with the addition of Surgespanner, as it gives a flexible sort of removal. Worldly Tutor is a very flexible card in any creature-base deck, and since you are running Craterhoof Behemoth, it'd make it easier to find one of your finishers. Earthcraft is pretty good in creature-based decks, too.

Regarding removal, there are two cards that either do not synergize with what you are trying to do (cast merfolks and abuse your commander's abilities) or have underwhelming abilities themselves. Those two cards are Thassa, God of the Sea and Zameck Guildmage. At 3 CMC, Thassa doesnt curve well with your commander and it doesn't synergize with it. It does very little in the early game, too, and you'd be better off with a spell that either draws you cards (instead of scrying) or generates mana to set up big plays after T3, like Cradle/Rites. Zameck only synergizes with the last activated ability your commander, which let's be honest, will hardly ever be activated (we rather draw cards and dig for craterhoof, right?). I understand that some of your other spells pu counters on creatures but you also need to pay to draw with Zameck, and it's colored mana on top of it. Seems very inefficient and I'd definitely cut it to make room for other spells. Another spell that seems underwhelming is Beastmaster Ascension. It's a bad version of Craterhoof Behemoth, so instead of it, I'd probably run Worldly Tutor to get hoof. Lastly, Cryptolith Rite is a fixed version of Earthcraft, but if you can run the broken version, I'd go with it instead.

All in all, you already have a pretty fun list that should make for an enjoyable casual game of edh. Good luck on your future games!

You're probably gonna need like 35-40 lands in an EDH deck anyway, so there's that.

Gifts Ungiven, unfortunately, is not EDH legal (full banlist here: Maybe you can consider Intuition as a substitute?

You also can only have duplicates of basic lands, so you're gonna have to cut out a Lightning Greaves and a Diabolic Tutor.

Strategy-wise, maybe you can consider things that make Mirko Vosk unblockable such as Aqueous Form, Thassa, God of the Sea, Whispersilk Cloak, and Protective Bubble so that he hits his intended target more often for more mill.

Coastal Piracy and Bident of Thassa would be great, not to mention Thassa, God of the Sea herself. Another nice interaction Ive found is Captain's Hook and Captivating Crew. Steal their fatty, equip/ attack, unequip and their fatty dies

lukas96 as far as the Aether Vial and the upgrades to the mana base those are both great suggestions and would definetely help the deck, however they are abit over budget (but if you have the funds I would probably take out the Merfolk Sovereign and Deeproot Elite). In regards to Thassa, God of the Sea I feel like building up the devotion would be difficult by turn three while running Simic and playing a three drop that doesnt to do anything until your next turn Isnt great for a tempo deck. However there are a lot of slower value cards coming out such as Kumena, Tyrant of Orazca if you know of any value fish that could help the slower strategy of this deck I would be happy to take any suggestions!

Well Aether Vial would defenitely make the deck better. If you can or want afford them you should get a playset.Also the Mana base needs a few upgrades.

4 unclaimed territory Fastlands, fetchlands, shocklands and mutavault would be great but they are a bit costly of course. Have you thought about a one of Thassa, God of the Sea
