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.)

Thegloomyg well I won through an infinite mana Blue Sun's Zenith into Thassa's Oracle but there's only one or 2 ways to get that combo off. Otherwise it's just value town

Hey! So there are actually various ways that this deck can win, and a lot of them don't require a whole lot of setup, just good tutoring and keeping the right cards. All 4 of the combos (Angel's Draw, Bomberman, Dramatic Scepter, and Thassa's Consultation), are win conditions. With Angel's Draw, you cast Angel's Grace first and just draw whatever you want with Ad Nauseam . Bomberman is an infinite mana combo because Auriok Salvagers lets you return Lion's Eye Diamond . Dramatic Scepter is also infinite mana as long as you have 3 mana in the form of mana rocks and mana dorks, you simply exile Dramatic Reversal with Isochron Scepter . Thassa's Consultation is (arguably) the easiest way to win the game, cause it only costs 3 mana and it's pretty hard to stop unless they have counterspells. Simply play Demonic Consultation and name a card that isn't in your deck, you'll exile your entire deck, and then play Thassa's Oracle and you win the game. Of course usually with infinite mana you'll just be drawing your entire deck out with Thrasios, Triton Hero and you'll usually be putting that infinite mana towards Walking Ballista .

Usually if you're wanting to win you'll be looking for 1-2 tutors in your hand, and a piece of a combo, that way you know how you're gonna do it. Aetherflux Reservoir isn't so much a win condition as it is a great way to bypass decks that eat at your life total, because you also tend to hurt yourself a lot. It just gives you some insurance so when you do finally cast that something big, if it gets stopped you at least have a backup.

As for ways to get to the combos, you'll be looking at any tutor of course, and Birthing Pod is an excellent choice for getting out a creature that you really don't wanna be countered. Usually before you win the game you'll want some form of insurance out on the battlefield, so if you have a win con in hand, the pod, and a one drop mana dork, I recommend using pod to get Grand Abolisher out, cause then they can't stop you from winning the game.

Finally, if you're in a situation where ballista isn't gonna win you the game and next turn you'll lose, or if you simply don't have a way to get oracle out or win by damage, there are ways to simply take over the game with things like Memory's Journey , Noxious Revival , and Windfall , or Timetwister . This is simply a combo that if you have infinite mana and Thrasios out, you'll be able to have infinite of every card in the deck, cause you get to shuffle your graveyard over and over again, and don't forget that if they destroy your infinite mana source at some point you can use Hullbreacher to generate some treasure tokens with this. All you have to do is use either Windfall or Timetwister, shuffle everything basically, draw your cards, use Noxious Revival to put it back on top of your library, draw it, use it again, then Memory's Journey to put Noxious and your card of choice back into the deck.

If you have any other questions, just let me know!

zAzen7977 on PHYREXIAN DOOMSDAY - K’rrik Combo (cEDH Primer)

Profet93, thanks for the +1 and your comment! You bring up some important points.

I’ve optimized the deck for Tainted Pact . I can use it to search for any particular card I need at the moment to complete a combo, since I only have 1 of each card in the deck. If I can steal an opponent’s Thassa's Oracle with Praetor's Grasp (which is more likely than not if an opponent is running blue), then I can cast Tainted Pact , naming a random card not in the deck, and exile my entire library for the win. I can also set this up with Doomsday , as I explain in the primer.

I considered Contamination , but the creature sac requirement prevents me from keeping it in play for long, since I run only a few creatures. Infernal Darkness accomplishes the same objective but I can keep it around a turn or two as necessary by paying life during my upkeep with K’rrik. The goal is to protect myself for at least 1-2 turns while I assemble a combo. You are right that Defense Grid is more effective during the early game, but this build is designed to win asap, and I rarely ever reach the late game where this becomes an issue.

You are also right that Drag to the Underworld is a lesser removal spell compared to others. However, in this build I mulligan aggressively to ensure that I can cast K’rrik within the first 1-3 turns. With K’rrik on the field I meet Drag’s devotion requirement, so I only have to pay 4 life and 0 mana with K’rrik to destroy any creature. Hero's Downfall requires at least 1 colorless mana to cast. I’m thinking in terms of speed, since each mana I have should go towards the 3 mana I need to cast Bolas's Citadel once I pull off Doomsday . So I would rather pay 0 mana to kill a creature with Drag and save my mana for Citadel.

cEDH is more of a mindset entering the game, than it is a deck definition. cEDH tables will assume every other deck is as powerful as possible, and do anything necessary to efficiently end the game in their favour as soon as it's able to. That's why by far the most interaction in cEDH is counterspell-like more than wrath- and doomblade-like. There's plenty of cheap, two card combos that can end a game, currently the most popular and efficient wincon is Thassa's Oracle + Demonic Consultation / Tainted Pact . Put the oracle trigger on the stack, exile your deck, let the trigger resolve, and win the game even if they remove the oracle. Creatures beating face is a slow, inefficient way to win the game, gathering 120 damage on opponents just takes longer than tutoring out two cards and playing them.

Casual, focused, and even optimized decks usually just want to "do the thing" envisioned in deckbuilding; play tribal, play a janky 5-card combo, voltron someone to death with all the equipment, proliferate all your planeswalkers and collect the emblems, etc; as many objectives as there's players probably. Everyone steps into the game to have a fun time, see their cards at work, enjoy the game as much as trying to win. This is where the social contract and the salty cards lists come in.

A deck that combos off at turn 2, or blowing up all lands to prevent your opponents from playing magic, being able to counter every spell, Windfall + Hullbreacher ... These things offer a different kind of fun, the fun to try and win, or at least dominate, the game at any cost. Like you'd do in Legacy. That's where Ramble's 60 card grind objections originate. If that's the plan you expect from all opponents, you'll adjust the interaction you include to combat those strategies, just like you'd adjust the number of boardwipes in your deck if everyone around you will play tribal creature decks.

For deckbuilding decisions, this basically means you're going to ask yourself for every card: "is this the best card I can play to help me end the game in my favour?". You'll never play a Worn Powerstone if you could play Mana Crypt . You won't include your pet card Archangel Avacyn  Flip just because it makes you think of the time you dominated fnm in 2016. Every card has a purpose, and is optimised for that purpose. Even on a budget, that should be your guidelines for building your deck.

MDFCs, however, are seldom best in slot. Their strength lies in never being worst in slot, because if one side is terrible, the other one can be useful enough so you don't topdeck something useless when you really need to hit action. Bala Ged Recovery  Flip is a bad Regrowth on one side, and a bad Forest on the other, but will never be dead in hand because of the versatility. cEDH decks are usually not looking for effects like this, because taplands are horrible for swift and efficient play, and actually playing Regrowth would save you the mana to actually cast that winning spell you're getting back from the graveyard. So Mcat1999 's presumption of: one or two could be good enough, but they usually won't make that much of a splash on the highest power levels, is probably accurate, at least for the MDFCs printed until now.

I would consider the classic infinite combos:

Isochron Scepter + Dramatic Reversal + 3 mana from artifacts = infinite mana.

Basalt Monolith + Rings of Brighthearth = infinite mana.

Leveler + Thassa's Oracle = win the game.

ASalesman on Unesh, Ultimate Guide (Tribal)

LONG TIME SINCE AN UPDATE, BUT HERE ARE SOME UPDATES:

  • Kozilek, Butcher of Truth replaced by Sphinx of the Second Sun . I recently realized that Kozilek can sometimes really hinder your strategy to deck yourself with. If you pull Thassa's Oracle and Kozilek in the same BFOF, it can be real sad sometimes. Sphinx of the second sun offers immediate value the turn you play it, has a lower CMC, AND it is a sphinx. The only downside is if you are trying to win with Nexus of Fate combo, he can't be on the field, but you could set this up with relative ease.

  • Mind Stone replaced by Jeweled Lotus . This one hardly needs an explanation. Jeweled Lotus is SO good in Unesh, because it allows you to play him really fast sometimes. Mind Stone is really lack luster compared to it, the draw effect doesn't make it worth keeping in the slot.

  • Thassa, God of the Sea replaced by Thassa, Deep-Dwelling . After play testing this, I like the value that Deep dwelling generated mor than God of the sea, even at the increased CMC. If your hand is somehow dead at the end of the turn, Deep-dwelling's ability will really save you (provided a sphinx is on the table).

  • Lonely Sandbar replaced by Glasspool Mimic  Flip. The cycling on sandbar is underwhelming, I'd prefer to have the versatility of being having another potential sphinx instead.

Short answer: Power creep.

Long answer:

Lots of new product is coming with some exceptionally powerful cards; whereas you use to have to spend a pretty penny to get any sort of power. Pre-cons have drastically upped their game.

Usually, when you start a game now you'll want to discuss what it is your deck is trying to do - you don't have to give everything away by any means just the jist. Lots of the newer commanders just provide out right better engines and the upper power levels have gone from the turn 2 Hermit Druid deck to the turn 1 Thassa's Oracle + Demonic Consultation decks.

Also, you may want to provide a bit more context about your decks and the decks you've faced - we can probably give you some recommendations that will help.

Hey there multimedia,

There is no budget for upgrading right now, even tough at the moment this deck is on hold since my Jodah (Jodah Archmage Eternal Budgetish deck is getting a few upgrades recently ( Rhystic Study and Thassa's Oracle so slightly expensive upgrade for that deck)

Copperhorn Scout this card used to be in the deck, but I didn´t really find much use out of it to be honest, but it is certainly in considering cards.

Thank you for your opinion, and I will certainly consider some cards. On card Staff of Domination I had my eyes already before a few times but I always forgot to order that one. So... maybe

Greatest problem this deck actually is going through is that there are no boardwipes and it struggles against flyers. I was considering Nylea's Intervention but that is also just among considering.
