Kiora's Eternity - Dual Infinity, and Beyond!!

Oathbreaker Competitive GU (Simic) Infinite Combo Jank



Other (1)

Becoming a Planeswalker is no easy task. For Kiora, however, it was as simple as stealing the Bident of Thassa . Now that she can Planeswalk the multiverse and command the oceans and their inhabitants, she has found a deep longing for something... more.

As a Planeswalker, her aging has slowed significantly. Merfolk are said to be long lived as it is, though not quite as long as their land-dwelling cousins; The Elves. Regardless, can Kiora live long enough to see herself become a Goddess?

The deck is very simple once you see what it does, though it can be a bit mentally taxing. There is literally only two things this deck does; Ramp and take extra turns.

We are going to start off a little bit slow and bring out dorks to flood the board. We do this and hopefully land some early draw cards until our engine gets going. Once we land on any one of our "Power Ramps", we can truly begin.

We use Kiora, Master of the Depths because her +1 will allow us to untap both a single creature and a single land. At first glance this may not seem impressive. But if we untap creatures such as Karametra's Acolyte , Elvish Archdruid , or even a Kiora's Follower we can really set off a huge amount of mana. We can also untap Nykthos, Shrine to Nyx or our transformed Itlimoc, Cradle of the Sun for immense amounts of mana. Kiora's Follower will be even more powerful if we can pull out a Doubling Cube .

We are looking to use this immense amount of mana to constantly play Karn's Temporal Sundering . We choose to run this particular Time Walk -esque card because it will allow us to pick off our opponent's boardstate one precious permanent at a time.

And yes, this card is going to get E.X.P.E.N.S.I.V.E but that's why we run the cards we do. Especially with Vorinclex, Voice of Hunger , Doubling Cube , and Kruphix, God of Horizons .

Make no mistake about it; You will be playing by yourself for quite a long period of time. I hope you brought some lotion ;) Don't want you to get callouses from all the card draw you'll be doing, hehehe.

Joking aside, I've kicked this deck off on T4 and went solo ever since. The thing can pack one serious punch. We don't really have a need for win conditions as Karn's Temporal Sundering will inevitably leave our opponent open and we can pick their life total off from there. However, I threw in a Craterhoof Behemoth , for good measure :3

EDIT: I don't really need Wilderness Reclamation as I don't have Instants / Abilities I can activate during my end step. So I shall be replacing this with something, though for the moment I do not really know what. If I can get another card that lets me untap lands, that'd be awesome. Otherwise, another draw engine. Maybe Horn of Greed ? I'm not really sure. I suppose since I am going to be making tons of extra turns I could always do Helm of the Host and make copies of my large Devotion creatures or my big mana dorks?





Turn 4. Two hard casts of Karn's Temporal Sundering .

Seriously, please ban Kiora, Master of the Headaches .

During another playtest where I was seeing the impact of Doubling Cube , I ended up having the perfect two-card combo for the deck.

Bare in mind I was able to bring out Kiora on T3 and get a single extra turn. Once that happens, it's pretty much game over man, but a T3 Kiora + Sundering is an exceptionally rare event.

On the battlefield, I have 8 small creatures, 8 lands on T7 because I have a transformed Itlimoc, Cradle of the Sun as well as a Gaea's Cradle and a Doubling Cube , WITH Karametra's Acolyte , Birds of Paradise , Elvish Mystic , Llanowar Tribe and Devoted Druid . Saying I have ramp is an understatement.

In my hand were two cards: Forest and Rites of Replication. I had considered using Rites on Acolyte for hilariously immense ramp, or perhaps Birds to add a butt-load more blue to my pool. However, I ALSO had Horn of Greed ; Another artifact I've been playing around with in this deck. Wanting to see what my Forest would yield me when played, I decided to do that before casting Rites.

So when Craterhoof Behemoth enters the battlefield, he becomes my 9th creature. Everybody gets +9/+9 and Trample. Nice. But I'm not done yet. I cast a Kicked Rites on Hoof.

Five more enter.

Now I have 14 creatures, all getting an additional +14/+14... FIVE TIMES

Everybody just got +79/+79 and Trample.

Seriously. And this is not sarcasm. Kiora, Master of the Depths is honestly broken in this format. Please, freaking ban her. T3 infinite turns + 6 Craterhoof Behemoths ?? This thing isn't just gross, it's demoralizing. Lmao!

I'll admit, I kept Cloudthresher in because I didn't really know how to search for high devotion creatures on Gatherer. Now that I figured it out, I found two viable options;

  • Gigantosaurus : Who costs 1 CMC less and is a 10/10 vanilla creature. Surely each combat I can swing and at the very least start clearing the board one persistent threat at a time. However, the aim of the deck is to string together an eternity until you go so wide or so long that your opponent just scoops. Swinging with a 10/10 is awesome, but I think we can do one better.

  • Rushwood Elemental : The reason I like this option more is because it grows passively. Yes a 10/10 is absolutely game-winning, but a 4/4 is enough to stomp most creatures into the mud as it is. By the time it can attack next turn, it'll be a 5/5 and therefore win most combat interactions. At a certain point, there is such a thing as a creature being too big. I know, seems impossible really. But the fact of the matter is, if your opponent is at 12 life and has a few 2/3s and 1/1s on the field with perhaps a 4/4, whether you have a single and static 10/10 vanilla creature or a 5/5 that will become a 6/6 next turn doesn't really matter - especially when the next turn is going to be yours for a while ;)

So! Rushwood Elemental is now in and taking over that Devotion slot!

Also, Cloudthresher kills Birds of Paradise :c

I added a better coloration of lands and threw in Jace, the Mind Sculptor because I had the room and it dropped from 100% competitive to just a mere 93% competitive lol.

Okay. Well, if you want the BUDGET version that is "more competitive", I guess just go with 10x Forest and 11x Islands :p hahaha

There are probably a few ways to do this, but here is one that I found:

Here is another T3 I just landed with exact cards.

I'll be honest here, I put Jace, the Mind Sculptor in for two reasons:

  • Boost the $$$, for the lulz
  • Make it "more competitive"

But he has nearly zero synergy with the deck and I often find that I never even play him because of that very reason. So I am looking to replace Jace with something else.

As a user suggested in the comments, Seedborn Muse is a good fit if I get her out early. However, later in the game she loses impact as my opponent won't have their turn come around for Muse to work. A good suggestion though, nonetheless. I am keeping options open for Jace's slot in the meantime, however.

In this panel, we will be listing all potential cards who will fit and what they might be able to accomplish for us!

I replaced the aforementioned Jace with Argothian Elder :D

Same CMC, less color restrictive, and holy hell this ability. Need I say more? ;)

I am looking to replace Blighted Cataract and Blighted Woodland as I feel they ask for too much mana for too little return. In some decks they are great, don't get me wrong. In this deck, I need mana available for casting creatures and for casting Karn's Temporal Sundering .

Given that I now have several methods to untap my lands, Lotus Field will be added.

Considering the high number of Elves in the deck, I am also adding in Wirewood Lodge .

Argothian Elder + Wirewood Lodge + any of the following:

Welp, that does it. Oathbreaker is solved. Infinite mana + infinite turns? Go home people, nothing to see here.

God I love this format <3
