Caves of Koilos Discussion

lagotripha on "Oh Baby a Triple" Counter Rites (Help Needed!)

Decide if you want to be valuetown goodstuff (and what type of that) or counters synergy.

Get a playset of Caves of Koilos/Llanowar Wastes/checklands, it'll let you play anything in these colours, even if it'll cost a bunch of life. As a stopgap, get a full playset of Crumbling Vestige- its cheap and will let you knock out a 1-off spell.

If you want counters synergy a full set of Winding Constrictor and Hardened Scales, then play a bunch of Servant of the Scale and Simic Initiate. Kudzu only looks amazing with fetches, so let it sit out. Cut abzan charm and Abundant Growth- Golgari Charm in the sideboard if you need it. If you're keeping it budget, Scrounging Bandar and Mindless Automaton can make a good draw engine.

If you want goodstuff valuetown Gurmag Angler, the card tearing up legacy, is your friend. You don't have the fetches to make him and taisugir broken, but Grisly Salvage, Treasured Find and Satyr Wayfinder can help, especially if you exploit some other graveyard synergies. Remember that in this space you will be competing with Tarmogoyf and Grim Flayer, and they will eat most creatures.

Alternatively, go all in on the Siege Rhino plan, and play a blink deck- Staring Contest: A List of Blink-Effect Cards has a good list. Thragtusk and rhino, as soon as possible (manadorks) to stabilize and start getting value from blinks. Eternal Witness and Dusk Legion Zealot/Elvish Visionary will be good engine peices.

Plan your sideboard, and put it up here. It'll help you stay more focussed in the maindeck, deciding when you need 4-ofs and when you need just one copy, and let us judge what needs tinkering a bit better.

theMarc on Atraxa, Praetors' Voice - Heavy New Phyrexia Theme

2 weeks ago

The Caves of Koilos are an important part of the history of Phyrexia, being the location of the portal that brought Yawgmoth to Old Phyrexia in the first place, setting in motion the beginning of the Great Work.

Planar Portal can be expensive to cast and to use, but it can be worth it. If you end up using it, I recommend the Invasion version, due to the flavor text.

Skeletonkey8 has the right idea with Rout. The new art shows Elesh Norn, and the old art shows Phyrexian forces overrunning Benalia, so either version works with your deck's flavor. Life's Finale is another Phyrexian boardwipe. And Damnation is ambiguous enough that it should fit.

I'm sure you're aware, but Dominaria gave us Phyrexian Scriptures and Yawgmoth's Vile Offering.

The Phyrexia's Core/Spine of Ish Sah combo is on-theme. The Core will also give you another way to sacrifice your Wellsprings.

Persecute (Urza's Saga version), Tsabo's Decree, and Extinction can be good, depending on everyone else's decks in your playgroup.

Finally, don't forget that the plane of Rath, the Rathi Stronghold, and the Evincars were all part of the Phyrexian war plan. Guys like Volrath, Crovax, Greven, and Vhati all worked for the Phyrexians, so you can include cards featuring/mentioning all that. Of note are Volrath's Stronghold, Hatred (fun with both infect and a lifelink general), Endless Scream (also fun with infect), Reanimate, Vhati il-Dal (fun with -1/-1 counters), Tortured Existence, and the original printings of Reflecting Pool and Propaganda.

(Wow, this post ended up longer than I originally intended it to be.)

I have a few suggestions:1. Check the name of your commander; you're missing an 'l.'2. Get rid of Caves of Koilos, Orzhov Basilica, and Orzhov Guildgate. You can't have any cards with a color identity other than Green or Black.3. SporeFrog is free experience for Meren.

Looks like a good deck! As for suggestions, have you considered maybe playing Caves of Koilos/Llanowar Wastes and Battlefield Forge/Shivan Reef instead of the Evolving Wilds? They will only get you 2 of each of your mana symbols, but they won't come in tapped. Also, what are your thoughts on Matter Reshaper?

Glad you like it! I can confirm you that the deck is indeed very fun and easy to play.

Playing with three colours can be a big deal in terms of budget, since you have to start investing some money in the manabase. Luckily, there are a few budget solutions in the form of painlands (Battlefield Forge, Caves of Koilos and Sulfurous Springs) and fastlands (Clifftop Retreat, Isolated Chapel and Dragonskull Summit, which are all relatively cheap. Exotic Orchard is one of my favourite budget lands, since in multiplayer it is basically a second copy of Command Tower. You can consider it a cheap alternative to the more expensive Reflecting Pool and Mana Confluence. As for shocklands and fetchlands, you can definitely start playing without them and get them over time. I wouldn't recommend, however, including too many lands that come into play tapped (like guildgates) because we can't afford to lose tempo with this kind of deck. Until you get the more expensive dual lands, basic lands are the way to go. Throw all the signets in, as well as a Chromatic Lantern (this one here is truly mandatory in three, four and five-colour decks), and your manabase should be fine. The rest of the deck is moderately cheap. While some cards like Bloodline Keeper  Flip and Anointed Procession are must-haves, you can find budget alternatives to a lot of the other cards (just to give you an example, Boros Charm or Rootborn Defenses do a decent impression of the more expensive Teferi's Protection).

Good luck building your deck and thanks again for the feedback!

FlammendesSchwert on Black and white Beatdown

thank you. I also playtested. Sword of Light and Shadow is very powerful against my deck.Chittering Rats I didn't know until now. it is a good card.

I see you only have one source of colorless mana, when I playtested, white mana was also scarce.What about 4x Caves of Koilos insted of 2x Plains and 2x Swamp ?

If you like playtesting again, try this sideboard version:

this will be very hard to pull off especially with the land base. and the 2 color mana casting cost. try finding cheap dual lands.

something like Caves of KoilosSunpetal GroveLlanowar Wastes

luckily Windswept Heath is one of the cheapest fetch..

Temple Garden is one of the cheapest dual lands as well. and if you are really on a budget go for dual color 1st. then slowly upgrade your deck. :)

Nice! I like lifegain Karlov a lot, been considering building him.

Glad you already have Well of lost dreams and Sunbond because those were my first suggestions.

Cradle of Vitality is very good with Karl, and you'll want the commander staples Swiftfoot Boots and Lightning Greaves to protect him.

Blind Obedience is good control and more lifegain triggers.

Vona, Butcher of Magan is a great compliment to the commander and a good lifegain payoff. This is important because why gain life if you can't use it to your advantage? Along that line of thinking, Phyrexian Arena and Necropotence are great card draw engines, and Phyrexian Reclamation is great recursion.

Since you have no mana base yet, I'll finish up with that. Pristine Talisman, Crypt Ghast, Scoured Barrens, Bontu's Monument, and Radiant Fountain will all get you some life triggers. Orzhov Signet, Command Tower, Orzhov Basilica, Tainted Field, Caves of Koilos, Isolated Chapel, Temple of Silence, Opal Palace, Terramorphic Expanse, Shambling Vent, and a bunch of plains and swaps to equal about 36 lands.

Hope some of this helps!
