Massacar on Gallia, and the Dance of Madness

"Ah we can dance if we want to, we can leave your friends behind, Cause your friends don't dance and if they don't dance, Well they're are no friends of mine..."

Would Manabond be a good fit for you? It combos with the Library of Leng and kind of plays into your already existing self discard strategy. Also maybe an Elixir of Immortality to get your grave cycled back into your library if need be.

Hi Pikobyte! Yes, I play this deck all of the time, and it's disgusting! This isn't a CEDH deck, but it wins a disproportional amount of time versus other 7-8 power decks. I am happy to address your feedback.

The most important thing to remember is that this deck draws an insane amount of cards, and it also gets to see an insane amount of cards. Rielle and Library of Leng are just two cards in a 100 card deck, and they are both very cheap to cast. In a typical game I see anywhere from 40-80 cards, playing game pieces that will help me win as fast as possible, and allowing the rest to go to wherever they are going, whether that's the graveyard or the library. It is very easy to tutor, draw into, or recur a relevant wheel for Rielle, and she also negates the only downside of Song of Creation (admittedly a pet card of mine; Teferi's Ageless Insight would likely be better for that slot). This deck spends early turns trying to set up a single turn where you storm off and win, and it accomplishes that through massive card draw and card selection. These two cards are just tools to accomplish that. The other important thing to remember is that there are only two no-max-hand-size effects in the whole deck, so there is a high probability that you will be discarding cards to Rielle since you often draw three extra cards on your turn just from attacking with your commander. If Library of Leng is out with Rielle, you will still discard your hand to Wheel of Fortune, but you get to discard your important pieces to the top of your library; this still counts as discard, so you draw 14+ cards off of Rielle. From there winning is usually trivial.

Regarding Earthcraft, believe me, I debated a very long time about putting it into the deck. This deck runs 7 basic lands. If I had a Volcanic and Tropical Island, it would run 5. That is not enough basic lands to consistently ensure that I have basics available to use with Earthcraft, especially one of each color. The value of Earthcraft increases proportionally to three factors: the total number of basics, the total number of lands, and the total number of effects that let you play additional lands. The deck has 7 basics, 34 lands, and one additional land effect (Burgeoning). Not enough in any category to justify its use. You're absolutely correct that Cryptolith Rite is worse without haste enablers, but in my experience, players tend to draw a lot of cards without my help, making me tons of snakes that can tap when it gets back to my turn. I'm never on the "attacking with snakes" plan, so all of them having haste is of no consequence. I'm on the "sac'ing snakes for mana and damage, and sometimes tapping them for mana" plan. If you really want to, you can use Lightning Greaves to equip a snake for 0, tap it for mana with Cryptolith Rite, then move to the next snake and do the same thing. You also might be surprised at how many times 20+ snakes I made on my turn make it back to me on my next turn. Finally, Kinnan, Bonder Prodigy allows each snake to tap for two mana of any one color with Cryptolith Rite, but does nothing with Earthcraft. Earthcraft is for the land ramp decks; Cryptolith Rite is for the rocks-dorks decks.

Ok some cuts

Keranos, God of Storms look I like him but better in other decks

Venser's journal

Meishin, the Mind Cage

Ob Nixilis Reignited

Day's undoing you lose all your triggers


Not worth the 10 mana Jin-Gitaxias

Core Augur

Barbed Shocker had him I pulled him fairly quick

Strionic Resonator not relay worth it in you deck

you really need more counter spells to protect your board

drop damnation or Blasphemous act for a Cyclonic Rift nothing like overload rift at the person end step before your turn then you wheel on your turn game ending play.

You need a lot better artifact ramp and more of it I would drop to 34 lands yes chromatic lantern should be cut

You should be running the two drop mana rocks any combination of about 5 of the signet/talisman you will thank me later you are grixis that is your ramp these are generally pretty cheap Arcane Signet Talisman of Creativity Talisman of Dominance Talisman of Indulgence Dimir Signet Izzet Signet Rakdos Signet

Hey jaymc1130, thank you for your input!! I agree that Geth's Grimoire is very effective with Words of Waste. I initially questioned whether to include the Grimoire because of its cost, but your explanation sealed the deal for me.

Before I can answer your question in detail, I need to test the deck out more. I made several changes as suggested by abby315 and I think the deck is stronger now. I have encountered a lot of graveyard hate recently, and most of the other Black, Red, and/or Green discard-oriented decks I have come across use reanimation or depend on the graveyard in some way. I am attempting a different strategy with this deck to mitigate this weakness. Library of Leng is especially useful because it allows you to protect your discarded cards from Planar Void, etc. and draw them back at will with Necropotence.

Abzan is an interesting color combination for discard I haven’t explored before. I like your list and I found the comments very informative as well. While I agree with the analysis on your deck page regarding mono-color EDH builds (this is my first attempt at Mono-Black), I think Tinybones presents a unique situation due to its cost (playable turn 1), built-in draw engine, and win-con rolled into one. Put this together with consistent mana sources and a low mana curve, and together this may be a winning combination. When I have done more testing I will definitely let you know.

Yo Harrusakama,
Damn dude, those are some solid suggestions, no idea how I didnt think about the Thornbite Staff combo with the Ashnod's Altar. I also like the utility of the Bow of Nylea with creature recycling. The deck manipulation given from using Greater Good and Library of Leng helps improve an approach to limit card draws: it sounds counter intuitive but I am trying to keep creatures in the deck but this combo really fixes that issue.

I am curious though if the card ruling for Mirror Entity allows you to pay mana to make all your homies 0/0 creatures which die immediately? Nesting Dragon is flippin sweet and is made for this deck but right now it is out of budget so it will be wiggled in later on if able. The worst part about good suggestions is reworking the deck to make room for them :(

Cool deck idea! I'm also planning to build this commander with a dragon theme.

If you are open to it I have some suggestions I would like your input on too. first of Thornbite Staff would combo nicely with the Ashnod's Altar. Sac an egg for 2 mana, triggers staff to untap Atla Palani, Nest Tender, create a new egg with the 2 mana. (Repeat till deck is empty if you like)

I see you got some measures to put stuff back on top of your deck, cool! I'm afraid I'll end up with high cmc cards in my hand I cannot cast with the egg triggers. What do you think about Greater Good + Library of Leng?

Next up: Did you consider Nesting Dragon? free eggs when playing lands. Also Mirror Entity would be so good. It counts as an egg too since it's a changling. And when someone board wipes you change all your creatures to eggs for 1 mana!

Last off, since creatures will be pulled out of the deck quickly. I'm still looking for ways to get creatures from the graveyard back into the deck to retrigger it with eggs. I was thinking about Bow of Nylea which can put 4 cards back on the bottom of the deck. But more then 1 card with this effect would be nice.

Woah... just imagine if Karn, Silver Golem was in the deck. Chunky artifacts + Darksteel Forge with creature-Karn becomes "I have blockers for days." Mycosynth Lattice turns him into an Armageddon, it turns Forge into "Vandalblast? What Vandalblast?" Lattice also turns Unwinding Clock into a creatureless Seedborn Muse, turns Clock of Omens into "Tap any 2 things: untap a thing," lets Sculpting Steel copy anything, lets Mirage Mirror copy planeswalkers (which Rings of Brighthearth combos will let you abuse completely), lets KCI turn your whole board into a resource, and lets you use Nevy's Disk to hold everyone's board state hostage. Disk and forge are also ridiculous. Drop the Lattice on top of that two-card combo and everyone gets up and walks away.

Other cards I would highly reccomend: Cloud Key, Crucible of Worlds, Temple of the False God, Ghirapur Orrery, Vedalken Orrery, Helm of the Host, Prowler's Helm, Whispersilk Cloak, Library of Leng, Venser's Journal, Aetherflux Reservoir, Staff of Domination, Thran Temporal Gateway, Aetherworks Marvel, Arch of Orazca.

Snips500 on [PDH] Tatyova Combo

1 month ago

Hi, I just recently brewed up a Tatyova list that is aiming to be competitive and I wanted to ask about a few of your choices. I acknowledge that you have likely tested and played this deck more often but I am mostly curious about some of your card choices and the direction that you took this list. You can find my deck here: ~PDH~ When Lands Came to Value Town (Tatyova)

  1. Why do you include so much card draw? I actually run zero spells or otherwise that draw me cards other than lands through Tatyova. When I first was putting the list together I had a bunch in the form of Ponder, Gush, and so on but ended up cutting them for other cards.

  2. Some of your Land fetchings spells just seem bad. I don't mean to offend but cards like Nature's Lore, Search for Tomorrow, Shoreline Ranger, Spoils of Victory, Farseek, Kodama's Reach and Rampant Growth just don't seem worth it to me. Instead of some of these fetch spells, I run 40 lands. I was also surprised that you are not running Dreamscape Artist (Springbloom Druid just seems like a worse version). It's like a repeatable Harrow and gets you two Tatyova triggers. I would argue that that card is one of the most powerful cards in my deck behind Tatyova ofc and Mystic Sanctuary.

  3. I decided to include more utility lands such as Bojuka Bog, Khalni Garden, and Sejiri Steppe. This decision on my part to include these was in spite of some of them not being in Green Blue but I though their value outweighs that downside. Bojuka Bog for example is better than Relic of Progenitus in this deck because you can flash it in with a creature like Walking Atlas and exile a target players bin and draw a card like relic. The thing is though that Bog is repeatable through your creatures that bounce your lands. Sejiri Steppe is similar in the way that its repeatable protection for Tatyova or another important creature.

  4. I noticed you only ran 1 land bouncing creature. In my deck, these guys power much of the value. With them and Halimar Depths I can basically ponder each turn at least once, it allows me to repeat the ETB effects that I mentioned above, and It also allows me to get a land drop in if I missed one for some reason. Floodbringer, Oboro Breezecaller, Soratami Rainshaper are the ones I run in addition.

  5. Now a few suggestions I have: Whispersilk Cloak, Power Sink, Universal Solvent, Vines of Vastwood, Scaretiller, Explorer's Scope (This works well in conjunction with Adventuring Gear and Aqueous Form), Seat of the Synod and Tree of Tales can be tutored with Trinket Mage, Library of Leng, Stone-Seeder Hierophant/Krosan Restorer, Spidersilk Armor (So the majority of your board doesn't die to Shrivel, Electrickery or something like that and harder for Pestilence and Crypt Rats.) Also Snap can ramp you is you have a land that taps for two and same with Frantic Search if you do want to play cantrips. Another win-con that will win you the game as soon as you combo off is Sage's Row Denizen that is assuming that you are not using Mystic Sanctuary.

Thank you for hearing me out. I am sure that there is a good reason for many of the cards I just questioned and I am excited to hear them to understand your deck better. If you have questions about my choices and reasoning I would be more than happy to explain further. I am trying to make the best Tatyova deck that I can and just wanted to know why a list with a similar end goal is running certain cards that I cut out.

Lastly, I just wanted to say that after looking through your list I am considering running: Lull and Moment's Peace because sometimes this deck has a problem stabilizing early because my playgroup sees my deck as a very large threat. Merchant Scroll, I don't know why I was not running it. Mystic Remora and Rhystic Study are just too good to pass up and I probably should have been running them. I have just one problem and that would be cutting cards. I would apreciate it if you could take a look at my list and tell me what you think.
