Neotrup on Prismatic Geoscope and what counts …

2 months ago

@aznb01777 In the future, if you have any questions that need to be addressed, please submit them as new questions so they can be put into the new questions section for visibility. All the rulings I'll be listing will come from Prismatic Geoscope 's Gatherer page, and the rule from the comprehensive rules as of February 2nd 2021.

As was stated in this thread earlier, there are 5 basic land types as defined by rule 305.6:

305.6. The basic land types are Plains, Island, Swamp, Mountain, and Forest. If an object uses the words "basic land type," it’s referring to one of these subtypes. An object with the land card type and a basic land type has the intrinsic ability "{T}: Add [mana symbol]," even if the text box doesn't actually contain that text or the object has no text box. For Plains, [mana symbol] is {W}; for Islands, {U}; for Swamps, {B}; for Mountains, {R}; and for Forests, {G}. See rule 107.4a. See also rule 605, "Mana Abilities."

Having multiple basic lands of the same basic land type does not increase the mana produced by Prismatic Geoscope :

11/8/2016 How many lands you control of a particular basic land type is irrelevant to a domain ability, as long as that number is greater than zero. As far as domain is concerned, ten Forests are the same as one Forest.

Even though Snow-Covered Plains and Plains have different names, they share the Plains subtype, so they're not counted separately:

11/8/2016 To determine the number of basic land types among lands you control, look for the Plains, Island, Swamp, Mountain, and Forest subtypes among the lands you control. Count each subtype that appears one or more times toward the number of basic land types among lands you control. This number can't exceed five.

Note that the ruling specifically calls out that the number can't exceed 5. If snow-covered basics and regular basics were counted separately, it could go up to 10.

beets on Horde of Notions - Elemental Tribal

sorry for the double post but.... i just realized some more cards that you really don't want to be running currently. Prismatic Geoscope is extremely expensive for a ramp spell. i would try replace this with a cheaper ramp spell. a simple Rampant Growth or Farseek would do well here.

i don't know why you are running Murderer's Axe... is it because you want to discard cards? if so i would instead replace it with either Chainer, Nightmare Adept if you wanna stay budget, or Fauna Shaman if you're willing to spend more on this thing. both give great value, and synergize with your deck better than this equipment does. which would you prefer: discarding a card to give +2/+2? or discarding a card to cast any creature from your graveyard and give it haste? notice you could recast Shriekmaw for it's evoke cost of every turn. that's value!

or Wolf of Devil's Breach. this card could also be a wincon for your deck and am surprised not to see it among your list already.

Realm-Cloaked Giant doesn't fit in your theme at all unless you are running Maskwood Nexus. so unless you're going to put that in there, i'd replace it with another board-clear spell.

and finally, i forgot some really important elementals that you will WANT to run in this deck!

you really need some cheaper spells to cast on early turns... Ashling the Pilgrim and Brighthearth Banneret are both amazing. Ad Brighthearth is ramp, which every deck needs.

Slithermuse is another evoke elemental, and this one cast refill your hand! again, every deck needs to draw cards.

Animar, Soul of Elements is also HUGE ramp. worth the price.

Muldrotha, the Gravetide let's you cast so many more spells each turn! definitely going to be happy whenever you draw her.

Multani, Yavimaya's Avatar is just a huge monster..... paying for a creature with potentially 20 power is too cool to pass up.

alright i've chewed your ear off enough...... good luck and have fun deckbuilding!

Hi sSasquatch, thanks for tuning in! The majority of my wins come from

I haven't been able to play in a few months due to a long work trip but would definitely recommend the new Sakashima of a Thousand Faces if you aren't running it already. Happy caging!

This deck is just nasty, very good job. I've just finished my own Archelos, but am going a Landfall route instead of playing full stax. I still took some inspiration from a couple of your cards. Have you considered Freed from the Real as redundancy for Pemmin's Aura? Some more great cards for Durdle Turtle are Prismatic Geoscope, Borrowing 100,000 Arrows and Paradise Mantle.

In case you're interested, you can find my list here:

Mainboard Cuts: Worn Powerstone kinda sucks. I'd rather pay one more for Hedron Archive or even Sisay's Ring.

Cathartic Reunion is just better Tormenting Voice in your deck. Run Chandra hugging mom instead of Tormenting.

Cuts from the Sideboard listed cards:

Prismatic Geoscope: Running 18 basics means you might not always get 3 mana from it, more like 2. Eitherway I feel it's bad as a rock and lackluster as a cage target.

25 cards I'll suggest for <15$ (EDHREC TCGPLAYER listed prices, may be higher or lower):

  1. Final Parting: Double tutor, one to the yard one to hand. Good investment for 5 mana. It's no Buried Alive but we can't expect many cards to be. (Price: .90)

  2. Cephalid Inkshrouder: Discard which doesn't matter to make shrouded Mairsil? Hell yeah. (Price: 0.29)

  3. Soliton: Another U: untap is solid. (Price: 0.10)

  4. Forbidden Alchemy: Basically a draw 4 most of the time for 3 mana and can be flashed back if you discard it or mill it another way. (Price: 0.11)

  5. Pestilent Souleater: Can be a backup win con with a card or two that can also pump. (Price: 0.10)

  6. Blighted Bat 1 for haste is worth it when not having Anger in GY or Hammer of Purphoros on board. (Price: 0.05)

  7. Twisted Abomination: Get a land with it then give Mairsil regenerate for a black when his commander tax is too high. Can never have too much protection when the commander is the whole gameplan. (Price: 0.03)

  8. Magus of the Bazaar: Draw 5 for tap on Mairsil. What's not to like? (Price: .46)

  9. Etherium-Horn Sorcerer: 3 To replay Mairsil isn't bad. Also can just be a cascade card if need be. (Price: 0.15)

  10. Cinderhaze Wretch: Untap affect + can be used to disrupt enemies. Also can be used on yourself if you really want for some weird reason? (Price 0.26)

  11. Dreamscape Artist: Discard isn't a downside, and it ramps. Can be put on Mairsil as well if need be. (Price: 0.26)

  12. Vector Asp: B: infect is very strong. Especially with following card. (Price: 0.20)

  13. Spikeshot Elder: This plus infect is a gross combo. Even without R to deal 4 to any target is strong, better than lightning bolt! (Price: 0.21)

  14. Grinning Ignus: A way to bounce Mairsil that's ALSO ramp. Pays for a commander tax! (Price: 0.16)

  15. Frantic Search: Free loot isn't ever bad. Instant speed too. (Price 0.47)

  16. Sinister Sabotage: You don't have much interaction. These next 3 are just interactive pieces to stop your opponents from racing you. Sinister is a good counter that also can basically draw a card with Surveil. (Price: 0.12)

  17. Terminate: No regen for them! Instant speed kill. Nice. (Price: 0.44)

  18. Arcane Denial: Great counterspell that's not mana intensive. (Price: 0.46)

  19. Perplex: Either a counter, makes an opponent lose their hand, or you can transmute to tutor for a 3 drop such as Rings or Commander's Sphere. Very versatile. (Price: 1.24)

  20. AEtherize: Bounce all attackers is a good way to protect yourself, since you already have many ways to protect Mairsil. (Price: 0.23)

21/22. Isochron Scepter/Dramatic Reversal: With enough mana rocks infinite mana and with that you can win for sure. (Price for both: 5.30). I think it's a worth it investment.

  1. Whispering Madness: Wheel that can be repeated. With GY synergies it's amazing. 10/10 (Price 0.57)

  2. Chain Reaction: Boardwhipe most of the time. You need some mass removal. (Price: 0.67)

  3. Pyroclasm: Clears tokens easily. (Price: 0.16)

Total Price: $12.94

Some pump activated abilities may be a good other add.

DemonDragonJ on Why Does Nyx Lotus Enter …

DeinoStinkus, is that also the reason for which Prismatic Geoscope enters the battlefield tapped?

MrKillStar on Ayara Ping

8 months ago


I would cut Conspiracy, since most of your creatures are zombies anyway and little tokens you create, you could just sacrifice asap with Ayara/Conrad on board.

Prismatic Geoscope - read rules on Gatherer.wizards.com - its 5 mana rock, that enters the battlefield tapped and can produce only one mana = useless in mono color deck. Better go with Sol Ring/Mana Geode/Arcane Signet are better options for that.

I use Tortured Existence+Desecrated Tomb in my For the Void deck and its just pure awesomeness. Every activasion of TD triggers Syr Conrad's ability twice (one creature coming out of you GY, another one coming in) and DT gives you 1/1 BLACK bat token with flying (which matters for Ayara). Its also insant speed activation, so you can use them to create flying blockers and a lot of tokens to sacrifice. Add in Phyrexian Altar and you can go infinite with either Ayara or Syr Konrad.

Sanguine Bond - With weak life gain in this deck, I wouldnt bother with this. I would replace it with more ramp - Caged Sun/Black Market or Songs of the Damned (which would work even better with Buried Alive), etc.; Village Rites would be very nice card draw (of course Phyrexian Arena, Necropotence is a big thing too).
Liliana of the Dark Realms could be also pretty nice for ramp.
You can always keep Sanguine Bond and throw in more life gain stuff life Whip of Erebos/Dread Presence/Ivory Tower/Venser's Journal or graveyard hate cards like Crypt Incursion/Suffer the Past.


Woe Strider could be used as instant sac outlet for your Ayara, with a 0/1 WHITE token and scry 1 as a nice bonus.

Cabal Coffers,Lake of the Dead,Nykthos, Shrine to Nyx - also very good lands for mono black decks, just not for low budget decks. Urborg, Tomb of Yawgmoth - probably not worth it if you dont run that many non-swamp lands.

Cards I would cut off:

Forlorn Pseudamma - 4 cmc 2/1, that needs to be tapped and pay additional just to make 2/2 zombie seems not very good.
Piper of the Swarm - they only thing making rats is Piper and Plague of Vermin (which is ok though). Piper works much better in Ayara rat decks. In this almost zombie tribal deck, Piper just doesnt really fit.
Syphon Flesh - Very independent on your opponent's board state and number of opponents.. So its kinda 50/50.
Conspiracy - Unless you're going to do some shenanigans with making non-zombie creatures and tokens into zombies (I counted 10 things in total that are either non-zombie creatures or make non-zombie tokens), I really wouldnt waste a card space with it, unless you can do some absurd amount of tokens.
Prismatic Geoscope - as I already said above.

Narrash on Storming Legends - The Ur-Dragon

9 months ago

BLK-Swordsman ok, as far as I understand, PMs are an upgraded feature, so I'll try to reply here in the most efficient way. I'm going to assume you've bought the 2017 Dragon precon like I did, which is a good start. Scion decks play combo. You put dragons in the graveyard to one-shot your opponent. The Ur-Dragon is spawning dragons, as a result it's a casual deck. First things first would be upgrading the mana base. If your budget allows you to, grab 5 fetches (10 really isn't necessary). I guess the enemy fetches are better but I run the allied for budget reasons. Play the 5 triomes. Even without fetches I'm sure they're good enough but since I run the triomes with fetches I find them spectacular. I used to run 10 shock lands but someone did the math for me and if you play the triomes, 5 allied check lands + 5 enemy shocks are just as good. The only dragon which is also budget that is mandatory is Atarka. Scourge of the Throne is incredible too. You can do pretty much what you want when it comes to the rest. I recommend Lathliss, Utvara Hellkite, Silumgar. Terror of the Peaks is the new M21 dragon and it's huge. Ones I do run for personal affiliation but don't recommend playing are Dromoka, Kolaghan and Ojutai. I think the dragon package is where your personality shines so do what you want with it! I'd recommend having around 25 dragons, not 30+. Ramping is a priority, consider that with The Ur-Dragon ability, dragons start coming at 4CMC, potentially turn 3 with some ramp. Instead of mana rock, prioritize spells between 2 and 4CMC that lets you fetch a specific land type (to grab triomes or shocks). Mirari's Wake is incredible. I'm not a fan of ramp on bodies except for some exceptions like Faeburrow Elder (2 mana at worst),Goreclaw and obviously Morophon which makes our commander 4 mana. For a first version of the deck, Dragonlord's Servant and Dragonspeaker Shaman are good alternatives. Fill the slots with cheap mana rocks, around 2-3CMC, no more (except for Prismatic Geoscope which is incredible with the right mana base). All star artifacts are Herald's Horn, Chromatic Lantern, Dragon's Hoard for obvious reason and The Great Henge, the latter which can enter on turn 4 at the earliest thanks to our beefy dragons. Since they're heavy on CMC, haste-enablers are great. Check out the ones I run, they're all cheap I'm pretty sure, like the two boots (Dragon Tempest is the best card). You mustn't run out of gas so drawing cards is good, especially attached on ramp spells like Kiora. Again, most of my draw spells are cheap and either ramp or grant haste so take those too (like Temur Ascendancy). Rhystic Study is going to be reprinted, better that than Painful Truths for example. Depending on your meta you can choose the number of removals to run. Since we play big spells and rarely have open mana I'd recommend using pseudo-removals with synergy instead of hard removal like Utter End. As in removal on bodies, like Glorybringer, Sarkhan's Unsealing, Silumgar, Atarka. I run very few board wipes but they're one-sided and cheap (Crux of Fate and Earthquake). That should be it. In short, choose your dragon package. Play A LOT of ramp. Fill the rest with haste-enablers and card draws, even better when a card fulfill two roles.
