Thassa's Oracle

Thassa's Oracle

Creature — Merfolk Wizard

When Thassa's Oracle enters the battlefield, look at the top X cards of your library, where X is your devotion to blue. Put up to one of them on top of your library and the rest on the bottom of your library in a random order. If X is greater than or equal to the number of cards in your library, you win the game. (Each in the mana costs of permanents you control counts toward your devotion to blue.)

Thassa's Oracle Discussion

RNR_Gaming on New Yisan?

1 day ago

I know some of you are familiar with edh and have probably heard that Yisan lost his Titan status around Eldraine. Not being able to keep up with the partners or Kenrith/dockside really put a damper on things - people have moved away from the creature based value engines and focus more on the ETB powerhouses that are Thassa's Oracle and [[dockside Extortionist]. Anyways, SynergyBuild always hits me up every few months wanting to discuss mono green and we usually discuss where Yisan falls into things- this is a brew I think that is good for now due to the absence of decks that turn sideways or have creature based engines. I've retooled the stax pieces and cut back on some of the creature removal to stuff in a bunch of untap/unbound mana sheniaghans. ;) any tips or insights would be greatly appreciated.

My biggest gripe with your build is that it doesn't play 4 Recross the Paths. With Recross, you get to play the sideboard Coco combo (Collected Company + Undercity Informer + Thassa's Oracle) to get around Leyline of Sanctity, which is a meta sideboard card right now. This is the biggest reason to play Recross; as your deck is now you have literally no way to get around Leyline besides casting Street Wraiths and Spirit Guides. Recross also lets you play one or two Reforge the Soul, which just becomes "2 mana: I win the game" since you can stack a combo hand with Pact of Negation/Veil of Summer for protection underneath it.

That said, I think the blue splash for Force of Negation is unique, and Serum Powder helps with the loss of Recross. However I think you need 3-4 enchantment hate spells in your sideboard at the very least, because Leyline is really crippling.

This is the build of Charbelcher I'm playing right now: Flip Land Charbelcher! [ZNR]. It's great that there are a bunch of ways to build the deck.

I agree with all but not the Angel's Grace removal from sideboard. it's great for Thassa's Oracle decks. they cast oracle with empty deck and in response you Angel's Grace, pass turn, they have nothing to draw and they loose (that's the theory at least).

I know about Eidolon of the Great Revel i'm waiting to get a playset thank you.

My thought proccess about Abrade was that it hits both creatures and artifacts. seems like a good card, no?

Thank you for your comment!

I'd play a lot more than 19 lands in a deck that requires 8 mana to kill without setup and at least 4 mana to kill with setup which will be hard seeing as one of your combo pieces is a 2/2 creature. I'd go up to about 23 lands and add in a lot more cantrips (maybe a playset of Serum Visions). Since your combo is so expensive mana wise I'd also add a lot more control pieces (counters and removal since you're good on hand attack) so that you can make it to those later turns.

Also, I assume you're playing this deck because you really like this specific combo, but as an expensive 3 piece combo its super fragile especially for modern. You could play Inverter of Truth+Thassa's Oracle and win quicker, easier, more effectively, and with less mana while still staying in the same colors.

At quick glance, here are some recommendations I have for you based off what I see. Manabond to go with Storm Cauldron. Slow your opponents down with Overburden, Mana Breach And Flooded Shoreline. Add Patron of the Moon to sneak bounced lands back into play, with that said Amulet of Vigor becomes very helpful. Parcelbeast + Scute Swarm goes off hard especially with Risen Reef in play. Can end up drawing your entire library so Thassa's Oracle as a win con. Oboro, Palace in the Clouds is very useful in here. Just some thoughts. Good luck with your brew!

Starsky2814 on Omnath, A Song of Creation and Chaos

sean360, so far in my play testing, Song of Creation has been more helpful than not. Especially when I have flicker effects going and additional land play to abuse the mana out of Omnath, Locus of Creation. Casting cheap stuff to draw two has been such great value that even at entire discard it hasn’t been devastating. Side note, in a few games I had Teferi's Protection in hand to cast and avoid the entire hand from being discarded.

Metachemist, thanks for the great feedback! It has definitely helped spark a few ideas for inclusions. I did consider Chulane, Teller of Tales, Thassa, Deep-Dwelling, Thassa's Oracle and Zuran Orb in the beginning stages of construction of the deck, but later decided to have a heavier focus on beat down tokens. Your insight has made me want to kind of change the direction and include the suggested cards. Greatly appreciated!

Metachemist on Omnath, A Song of Creation and Chaos

Zuran Orb is a fantastic way to fuel up a massive game breaking scape shift. Thassa, Deep-Dwelling is a free flicker at End step. Roon of the Hidden Realm can allow you to refresh Omnath triggers via other people's turns. Same with Chulane, Teller of Tales combine either of the above with either Leyline of Anticipation and Seedborn Muse and every turn is your turn to slam down lands and pay them off with Omnath smacking everyone. With an ultimate finisher of Thassa's Oracle and you have all the goodness of a Bant flicker/Landfall deck combined with faster pay offs from Omnath to close out the game even faster.

Anyway these are just my thoughts of looking over your deck and thank you for letting me ramble.

Thousand-Year Elixir should probably be Concordant Crossroads I had someone respond to my explanation of my loop and casting of Thassa's Oracle trigger with an Angel's Grace he felt clever so I had to let him know that I also have a Concordant Crossroads to attack him down to 1 life point and Walking Ballista for the last point of damage on his upkeep so he scooped it up. Obviously that was in a vaccum but still figured I would mention it.
