gonz0pl on The Fateshifter | **PRIMER**

First of all, thank you for your Primer, it’s been a great help! Very inspirational piece of deck tech!

I’ve recreated most of the deck with some minor changes.

I’ve cut out Utter End in favour of Sorin, Grim Nemesis as a redundant effect in Aminatou + Kaya + Guardian + Panharmonicon/Oath of Teferi combo. He also provides extra draws, something the deck struggles with, in my opinion.

I reduced Islands to three, adding Halimar Depths. Having hardly any Turn 1 plays, I think it’s worth keeping a slightly riskier hand and re-arranging the top to hit the missing land. If you have a fetchland in hand, you can t2 reshuffle easily. I also found it helpful when I was running out of gas.

I decided to include Eldrazi Displacer instead of Ixidron, so also had to tweak manabase a bit. Swapping Concealed Courtyard and Darkslick Shores for Caves of Koilos and Underground River respectively brought the deck to a satisfying number of colourless sources. Displacer does not disappoint! I was able to pull of Felidar Guardian + Gonti, Lord of Luxury tonight, without Aminatou, the Fateshifter and Panharmonicon or Oath of Teferi. Instead, I had a Peregrine Drake and five lands, including Winding Canyons and Reliquary Tower. Took a while to explain to the table it’s a win lol!

I do not own an Imperial Seal so decided to go more flickery way and added Brago, King Eternal. The deck isn’t that much value oriented though, so I will probably add Rune-Scarred Demon instead as I found myself struggling to find answers at times.

Also swapped Angel of Despair for a cheaper disruption creature – Reflector Mage. More likely to get cast with Winding Canyons. I know it only hits creatures, but I didn’t find myself in the need to heavily disrupt non-creature strategies just yet.

Perplexing Chimera is still on my list. I like how you can get it back with Aminatou’s -1, but opponents will slow roll their spells in order to get rid of it or will simply wipe the board. Considering putting Draining Whelk as it’s a more reactive disruption that I can later flicker with Eldrazi Displacer or bounce back with Venser.

Insidious Dreams is proving to be disappointing as oftentimes I don’t have enough acceptable cards to pitch to it. Might go with Personal Tutor or Mystical Teachings instead. The first one if I can afford to slow roll Entreat the Dead or can use Aminatou’s +1 to put Time Warp in my hand, provided Archaeomancer or Salvager of Secrets is on the field already. The second can be good to fetch Venser, Shaper Savant, a counterspell or any other instant tutor effect. Flashback can prove useful too.

Thanks for sharing your deck with us, hopefully you’ll find my playtesting experience useful, too!

Well, I mean Bolas is one of the most power-hungry and powerful planeswalkers in the game, if that doesn't say cEDH I don't know what does, also RNG doesn't exist in Gemstone Caverns, IE no rolling dice or flipping coins, but if you just mean randomness, I could say the same thing for every card that you only want openning hand and is a bad draw later on, like Sol Ring, or the two leylines, or Mana Crypt.

The essence of Bolas is 'Everything to Win', so the cards like Mana Crypt, Mana Vault, Tarnished Citadel, Ad Nauseam, Imperial Seal, Mana Confluence, Shivan Reef, Underground River, Ancient Tomb, and City of Brass are more flavorful than cards like Izzet Boilerworks, and also are just good cards.

Jank is generally the opposite of competitive, so why every turn 4 win is supposedly jank, and Laboratory Maniac is supposedly jank too is beyond me.

Also, discard is a mechanic of stax, a key mechanic of that too, if you have ever seen a cEDH mono-black stax deck not running discard, be my guest. It is too powerful an effect not to use if your goal is to stop your opponents from casting spells.


Also, have you seen Nicol Bolas, Planeswalker? He ends games fast, not slow. I turn one any land and Lotus Petal to Flash+Arena Rector him out and it is over, no buts about it, that one player who might have an answer? +3 and their only land is gone, next turn do the same, next turn ultimate him, rinse repeat on the other two players who are still in the game, protecting him from Chain of Vapors and Into the Roils with the Counterspells in my hand, until they are all out of lands, cards, and permanents, and eventually life too, GG.

Also, the original Nicol Bolas, yeah I run him in modern, who else am I gonna turn one out with two Simian Spirit Guides, a Faithless Looting and Goryo's Vengeance, Emrakul, the Aeons Torn? Nah, he blows up their permanents, what permanents are they going to have turn one? Not much, discarding their hand is much better, but obviously I run both.


Point is, I don't think the essence of Nicol Bolas is to be a slow, grindy controlling deck, it is a deck that wins every time, for now and forever, sure, I'd probably argue grixis twin should be the deck for Nicol Bolas, but he'd only be used for the commander, and wouldn't serve a purpose in the deck other than for colors.

You also asked me for advice, so take it or not, but I got the deck to be more competitive and down to 100 cards, like you wanted.

You have 137 cards, you need to drop 37?

Okay:

Landbase drops/adds:

Drop all three temples, bounce lands, Sunken Hollow and Smoldering Marsh, Forge of Heroes, Command Beacon, the three lands like Sulfur Falls, Dragonskull Summit, Desolate Lighthouse, and Drowned Catacomb, total of 13 lands, but add City of Brass, Gemstone Caverns, Ancient Tomb, Mana Confluence, Tarnished Citadel, Gemstone Mine, Shivan Reef, Underground River, and Command Tower

Total loss of cards = 5, rest needed = 32

Mainboard additions I'd suggest?

Talisman of Dominance, Fellwar Stone, Talisman of Indulgence, Bottomless Pit, Dark Confidant, Snapcaster Mage, Timetwister, Ponder, Brainstorm, Laboratory Maniac, Demonic Consultation, Tainted Pact, Imperial Seal, Dismember, Chain of Vapor, Pact of Negation, Mystic Remora, Swan Song, Delay, Dispel, Liliana of the Veil, Jace, the Mind Sculptor, Chrome Mox, Mana Vault, Mox Diamond, Lotus Petal, and Rolling Earthquake.

Addition of 27 cards = 59 total to drop

Drops:

Xantcha, Sleeper Agent, Nicol Bolas, Planeswalker, Vedalken Humiliator, The Scarab God, Nicol Bolas, God-Pharaoh, Liliana Vess, The Eldest Reborn, Painful Quandary, Pendrell Mists, Mind's Dilation, Omniscience, Leyline of Anticipation, Hero's Downfall, Stunning Reversal, Rakdos Charm, Thrilling Encore, Countersquall, Desertion, Go for the Throat, Fraying Omnipotence, Hour of Devastation, Tormenting Voice, Torment of Hailfire, Syphon Mind, Disrupt Decorum, Dark Intimations, Cruel Ultimatum, Blatant Thievery, Beacon of Unrest, Blasphemous Act, Damnation, Bloodchief Ascension, Disciple of Bolas, Etali, Primal Storm, Nightveil Specter, Fell Specter, Blazing Specter, Augur of Bolas, Clever Impersonator, Jace's Archivist, Kess, Dissident Mage, Mystic Confluence, Disallow, Cryptic Command, Reforge the Soul, Megrim, Liliana's Caress, Entreat the Dead, Phyrexian Arena, Rhystic Study, Search for Azcanta  Flip, Dream Salvage, Chromatic Lantern, Expedition Map, Lightning Greaves, Worldgorger Dragon, Animate Dead, Gonti, Lord of Luxury and Glacial Chasm

That should do it! 100 card deck!


The biggest upside to my switches and drops is the extreme amount of lowering that is done to the average cmc of the deck, along with the droppage of slower cards that do little without other spells. The new gameplan would be use discard and disruption like countermagic and removal to stop your opponents just long enough to use Laboratory Maniac with Demonic Consultation or Tainted Pact to exile your deck, and usually a draw spell like Brainstorm. More tutors for consistent gameplay is in the switches too.

I mean for Eldrazi Displacer, the dual-painlands, HOU pain lands, and a couple 5 color painlands lands are all untapped colored mana producers that can also produce colorless, if you want.

The ones for this deck are as follows: Adarkar Wastes, Underground River, Caves of Koilos, Shefet Dunes, Ipnu Rivulet, Ifnir Deadlands, Grand Coliseum (not untapped sadly), and Tarnished Citadel

Ok. I didn't see you were running Death's Shadow, which I get. In this case, I suggest you s play set of Underground River to lower your life faster and get good mana fixing

Ok, so, first thing to do is to focus on what green cards you have that let you ramp. As said: Sakura-Tribe Elder, Explore, Utopia Sprawl, Farseek, Oath of Nissa, Search for Tomorrow, Birds of Paradise, Cultivate, Rampant Growth, Beneath the Sands, Burnished Hart, Dawntreader Elk, Expedition Map, Font of Fertility, Wayfarer's Bauble, Sylvan Scrying and Harrow are good options.
Of this, you should put at least 8 cards (I suggest Sakura-Tribe Elder, Birds of Paradise, Farseek, Oath of Nissa or Sylvan Scrying). I don't really like From Beyond, Blisterpod, Catacomb Sifter, Void Attendant, Warden of Geometries and Grave Birthing, since they cost too much and they let you have only colorless mana, thing that you don't need since you are three-coloured.
Then, as said before, I'd increase Gonti, Lord of Luxury and Ashiok, Nightmare Weaver up to 2x copies and I don't really like Nightveil Specter, alternatives could be: Circu, Dimir Lobotomist, Bribery, Praetor's Grasp, Psychic Intrusion, Stolen Goods. Oblivion Sower it's a funny card, I'd put in in 1x.

Another thing: You have some big creatures and you are black-green-blue, I'd increase your land number up to 22. Remember also to choose lands that could be searched when you are ramping (if you have chosen to ramp only with cards that search for BASIC lands, well, put at least 4x basic lands of each type). Some lands you could might consider: obviously fetch lands and schocklands, Darkslick Shores, Blooming Marsh, Botanical Sanctum, Drowned Catacomb, Woodland Cemetery, Hinterland Harbor, Fetid Pools, Underground River, Llanowar Wastes, Yavimaya Coast, Sunken Ruins, Twilight Mire, Flooded Grove , Sunken Hollow. For all the rest of the cards that could enter your deck, I'll wait to see if you like the direction your deck is going and, most important thing, what types of cards you have chosen to ramp, to be your manabase and wich cards will steal your opponent's cards.

Seems very nice, but I'd do some changes: first of all I would change Cast Down into Fatal Push. Then, if it's on budget, I'd increase the numer of Polluted Delta, Flooded Strand and Marsh Flats and I'd cut Nimbus Maze and River of Tears. I'd add also the schocklands, if on budget: Hallowed Fountain, Watery Grave and Godless Shrine, cutting Adarkar Wastes and Underground River. Then, why not a Logic Knot or Mana Leak instead of Negate and Pact of Negation? Also, since you have decided to use only 2x Inquisition of Kozilek, couldn't be better Thoughtseize? Another 2 token spawners I would take in consideration here are: Bitterblossom and Secure the Wastes (since is instant and creates as many tokens you want). Another thing: since you have only 4 black spells, why won't you consider cutting all black from the deck?

Llanowar Wastes, Caves of Koilos, Adarkar Wastes, Brushland, Yavimaya Coast, and also Underground River are powerful cards, and the life loss rarely matters. Tarnished Citadel, Forbidden Orchard, Gemstone Mine, and Reflecting Pool are also very good.
