Caves of Koilos Discussion

Oloro_Magic on Curse after curse

1 week ago

Your ideal mana base would look something like this in my opinion:

7x Swamp

4x Marsh Flats

1x Bloodstained Mire (or any fetch with black in it)

1x Godless Shrine

3x Shambling Vent

2x Urborg, Tomb of Yawgmoth

2x Isolated Chapel

4x Ghost Quarter

To make it budget remove the fetches and shock as well as Urborg and add Caves of Koilos and add some more swamps and Evolving Wilds if you have to.

Skoodly on Sometimes It Works!

After the retool, you might actually want a few sources that produce abzan or all color mana on the off chance that you can activate Lingering Souls's flashback. That's where the card's real reliability comes from imo. Mana Confluence and Birds of Paradise would work ok, but replacing each of a plains and forest with Caves of Koilos and Llanowar Wastes or similar duals is my best suggestion.

Oh also, I'd recommend Disenchant over Sundering Growth in the sideboard. The extra token can be nice, but Disenchant adds consistency, as it's easier to cast through enemy Blood Moon and Spreading Seas, and is easier to cast when you have a basic Swamp or Vault of the Archangel but want to cast multiple things that turn, and it doesn't need you to pay life to Caves of Koilos.

If they have any lands like Caves of Koilos it will be hard to secure the victory. Maybe add some way to make them gain life quickly.

Triton on Breya Budget

I'd recommend working on the land base, as it's an extreme game-changer when all your lands EtB untapped. I recently got all the shock lands for my Breya deck, and it runs so much smoother. I understand completely if you can't afford shocks (I'll leave out fetches haha), so I'd recommend using pain lands and check lands. Glacial Fortress, Drowned Catacomb, Dragonskull Summit, Shivan Reef, Caves of Koilos, and Battlefield Forge are all good lands under $2-3.

I'd also suggest Dispatch in the removal suite, since it's pretty easy to achieve metalcraft in the deck.

Reckless Fireweaver, Impact Tremors, and Disciple of the Vault all create infinite life loss/damage with Sharuum + Sculpting Steel/Phyrexian Metamorph. Bitter Ordeal can exile all opponents' libraries, if you can afford it.

Saheeli Rai goes infinite with Liquimetal Coating and Felidar Guardian.

Feel free to check out my deck for ideas/inspiration, it's more combo/control-focused, but I'm sure there are some staples that you may find use of in there:

The BREEya to My SCREEya

Commander / EDH Triton


Hope this helps!

Yes, Providence does set your life total, but I held on with Angel's Grace. So I brought my life total up to 26 twice; once at the beginning of the game and once via playing the spell with 1 lifepoint remaining.

I don't like Path to Exile because it gives my opponent a land. Declaration in Stone can remove copies and in the event that my opponent gets to investigate they would have to spend mana to use their clues instead of casting spells.

Diabolic Tutor is there to grab one combo piece. In the majority of my games I can easily draw into two pieces if I don't start with them. The lands are split down the middle so I don't have to worry about not having black when I actually need it, and I can trade in my black sideboard cards without adjusting.

Isolated Chapel is a great substitution for Caves of Koilos. Lately I've been thinking of just adding two more Snow-Covered lands to replace them though. With a 50/50 land distribution playing a land that enters the battlefield tapped can be a big detriment when I'm hoping to end the game on turn 5.

Rurara_Rahura Thanks for the explanation!

So I was just reading up on your competition notes:

"I held on in the third hand by having Providence in my opening hand and casting it on turn 7 after Angel's Grace saved me a turn. The Elves were fast and fierce but couldn't attack hard enough to overcome 52 lifepoints."

How did you get the 52 life points? Like I understand 26+26=52 (if you play two), but Providence makes your health 26 no matter what right?

Also, why 2x Declaration in Stone? Any particular reason? Why not Path to Exile when it's an instant and is only one mana. This deck is godlike.. The only apprehension I have with it is the mana demand of your primary cards and the possible need for more tutor or a cheaper tutor than Diabolic Tutor.

Do you think it would be fine for someone to add 2x Isolated Chapel to replace your 2x Caves of Koilos if they really aren't on a budget?

I know you're pretty much set on the deck and it's clearly kicking butt, I'm just picking your brain a little bit.. I'm more of a min-max deck builder guy. :-p
