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

CasualFocusedEDH92 on Atris Advisor of Thieves

The deck aims to take advantage of ETB triggers. We can repeat them with Thassa, Deep-Dwelling, Conjurer's Closet and Panharmonicon.

There are some powerful (infinite) combo's in here that can close out the game:

Duskmantle Guildmage + Mindcrank = infinite mill. With Memory Erosion on the battlefield this combo is even easier - as in, less mana intensive - to pull off.

Peregrine Drake + Archaeomancer + Displace or Ghostly Flicker = Infinite mana. Once we have infinite mana we can continuously blink Mulldrifter or Atris, Oracle of Half-Truths to draw our whole deck. Before winning with Jace, Wielder of Mysteries or Thassa's Oracle. Alternatively, we can mill all our opponents with Sphinx Mindbreaker (possibly turning it into damage with Mindcrank), or steal all our opponent's permanents with Agent of Treachery.

Of course, it is also fun to not combo off and just fill our opponent's graveyards, resurrect their stuff under our control and kill them with their own creatures.

Thanks for the answer. I took a look at your manabase. How are your experiences with Yavimaya Hollow? I asked me, why do you play Geier Reach Sanitarium. Probable as an answer for the Thassa's Oracle-Combo(?). Is there a reason, why do you play Geier Reach Sanitarium instead of Mikokoro, Center of the Sea? Are there any advantages to discarding cards?

So, here are my thoughts about the deck:

Manawise, your landbase should rather consist of lands that come into play untapped. It's important to have your mana available asap. I would suggest replacing karoo lands like Orzhov Basilica and also Opulent Palace with battlelands like Sea of Clouds and painlands Adarkar Wastes. The storage lands are also not ideal (e.g. Dreadship Reef), because they do not provide colored mana at start. And of course the more fetchlands you can add the better, missing Scalding Tarn, Arid Mesa, Verdant Catacombs, Windswept Heath, Wooded Foothills, Flooded Strand, Bloodstained Mire.

I would suggest you to cut even the three remaining creatures and add additional card advantage and lock pieces. Im missing Sylvan Library, Rhystic Study and Mystic Remora... all important ways to get extra cards.

Since your main wincon is the Consultation combos, I suggest you definitely run Thassa's Oracle as a main, cheap combo piece.

Lightning Greaves, boots and Helm are not necessary, since protecting Atraxa should not be such a priority to warrant extra cards for it. Also Mana Tithe, Mana Leak and Opt are not that relevant in a multiplayer format. I would advise to replace them with general, cheap countermagic, for better utility. Dovin's Veto, Delay, Swan Song, Tale's End can serve both to protect your cards and your combo, but also disrupt your opponents from winning.

From cheap, but relevant planeswalkers (besides Oko ofc), I would add Vraska, Golgari Queen and Kaya, Ghost Assassin. They generate a lot of card advantage over time.

Also with the amount of manarocks, you could play Winter Orb to stall and buy bit more time for your 'walkers.

DraconixCB on Make No Gravetide Image (cEDH Muldrotha Primer)

CarlosHentze I'm not OP, but I've been enjoying playing Muldrotha for a little while now.

Your first port of call will be trying to remove whatever it is that's causing you to not have access to Muldrotha, through whatever means are relevant. The combos in this list, at least, all rely on Muldrotha as a combo piece, and as such you'll not get too far without access to her.

If this proves impossible for whatever reason, your next best bet will likely be going on the Beatdown, using cards such as Razaketh and Nezahal to pressure people's life totals whilst using the rest of the deck to control the board as you usually would.

Depending on who you're playing against, and how the game has gone thus far, you might be able to use your Reanimate effects to win using other people's combo pieces. For example, if you're lucky enough to up against a Razakats player, you may be able to steal their Auriok Salvagers and use it to make infinite mana, winning the same way as normal. Obviously this will only be an option some of the time, but it's worth keeping in mind as a possibility should you need it.

If you're not following this exact list, then it's fairly easy to add other wincons such as Demonic Consultation and Thassa's Oracle, but those depend on how you wish to build to personal taste.

Oloro_Magic on [Primer] - Ad Nauseam Combo [[Procellam Legit]]

2 weeks ago

Flooremoji:

In practice there is no real difference between Ethereal Haze, Holy Day, and Darkness. Technically speaking Ethereal Haze does a little more in it's ability to turn off proactive activations of abilities some creatures have, i.e. Walking Ballista and others, but this isn't really something that ever comes up.

As for the mana argument, on average you are more likely to have access to white mana earlier and quicker (most players have the one Swamp be a second Plains to better illustrate this) but even then the difference isn't that profound and really my decision has come down to art in this case, I was more inclined to Ethereal Haze right now as I have played the others.

I will say though that sometimes having it be a white card is advantageous. Just by virtue of Ad Nauseam costing means that our combo is more intensive in that respect. Perhaps there could be a scenario where we have to fog and win that turn (I can't brainstorm what that would look like, perhaps our opponent is gaining a lot of life and we have no Thassa's Oracle left in the deck, ergo, we have to win with Lightning Storm in response to them gaining the life; more likely perhaps our opponent has Heliod, Sun-Crowned + Walking Ballista or Vizier of Remedies + Murderous Redcap + sac outlet about to be online, in this case we would have to win that turn in response anyway but Ethereal Haze shuts off some trickery I suppose), in this very specific circumstance we would want the fog that doesn't use the more intensive color necessary for our combo. Again though this is a wild hypothetical and very unlikely, really this is a matter of mana and art.

Vale,

Oloro

On the lands(vivid, Wilds/Expanse) cut em for basics. If you like the depletion lands cut some basics for them in the future.

Demonic Consultation plus Thassa's Oracle and/or Jace, Wielder of Mysteries is an 'I win'. Easy include if you just add Jace and Consultation, as Jace is on-theme.

This is my favorite deck of all time and my magnum opus. It's a monogreen list with Yeva, Nature's Herald at the helm. It has been geared and tuned to play formidably within the most current cEDH meta. It can win on any turn, phase, or basically any instance in which priority is passed. For that reason the deck list can get away with running cards like Heartwood Storyteller, which hard counter Ad Nauseam, Underworld Breach, or Isochron Scepter + Dramatic Reversal.

An opponent once went into an extensive counter war to resolve his Ad Nauseam, before it could resolve I casted Heartwood Storyteller. He drew half his deck, but upon attempting to combo off every single card netted the table a draw... eventually another counter war ensued drawing me more than half of my deck, once the player went for his Demonic Consultation with Thassa's Oracle's effect on the stack, I stormed off with an Veil of Summer + Allosaurus Shepherd protecting the most critical pieces of my combo.

You can check out the primer to learn how to storm off on other people's turn and actually win in Monogreen.

My favorite deck is a Kess, Dissident Mage deck that combos off using Demonic Consultation+Thassa's Oracle.

It's fun for me because of the diversity of all the cards while at the same time they do essentially the same thing: slow my opponents down until I can win by combo.

It's fun for me to always have an answer in hand to whatever my opponents play and the value in replaying spells.

A fun game I played once was a 1 vs 1 game with someone where I kept a 1 land hand and still won on turn five. I played a tapped land turn 1 and and passed. Turn 2 I got super lucky and topped decked a basic land allowing me to exile Simian Spirit Guide from my hand and tap out to cast both a Arcane Signet and another signet. I cast kess on turn 3 and cast consultation turn four naming Thassa's Oracle giving me the win on the next turn.
