The land count isn't that bad, some decks can run on low land counts. Look at all the non-land mana producers in this deck, it should be alright with the land count, no more than 32 land for this deck probably, and 30 is about the lowest I'd go. My only suggestion for the land base would be to put in more mana for your card with cards like: Ancient Tomb and Mishra's Workshop to get out your general faster. Beyond that, it's a solid land base unless you want to spend a whole lot of money on it.

For example, my animar deck runs on 32 lands (which I just increased from 31 rather recently), and it can combo out as early as turn 1, generally going off around turn 4 or 5 if it isn't interrupted.

The only thing that stands out to me is Unmake is asking to be replaced. I'd personally go with Oblation as it hits everything (and can tuck generals if needed), and it's only drawback is actually sort of a plus side, given your general. I mean there's some other cards that can be replaced with more expensive counterparts, but Oblation is a pretty cheap upgrade.

30 lands is too little; there's no debate. If you're not being punished for such a low land count, your meta is skewed or your house rules coddle bad deck-making decisions.

If each member of your regular playgroup played with Strip Mine and Wasteland (as mine do), the math would add up quickly and unfavorably for you. If every deck in your playgroup played Return to Dust, Planar Cleansing, Aura Shards, Austere Command, or Vandalblast (as mine do), you would understand the suffering that comes from bad land balance.

I also notice you play with risky, ersatz lands like Dimir Aquaduct. This is indicative of playing in a meta in which land destruction is utterly rare. That's quite a luxury.

This deck would have severe problems in a competitive meta, but in a casual meta might be playable - with a little luck.

Honestly, a lot of competitive decks don't run 1 for 1 land destruction in multiplayer because it is just as beneficial as targeted discard, It's not. You're slowing down 1 player and yourself, there's more people at the table you need to consider. If this was a competitive 1v1 deck, I'd agree with you; but it's not, which you can clearly see from the build.

He/she could probably up the land count a little and it'd benefit them, but if they don't want to, they don't have to, it is their deck after all. If it works for them, that's all that matters.

@nbarry223. Thanks for your comments and logical responses. Glad to see someone understands that there are other meta's between playgroups. I will be sure to check out your deck as well!! As for you bominous, I appreciate what you are trying to say about the land but if you've never tried running this deck, I don't think you understand why I'm doing what I do. My playgroup is a minimum of three people, usually four, and because of that my deck is built around surviving the wipes that accompany a multiplayer environment, say Wrath of God . As I also said, my playgroup frowns upon counterspells and infinite combos to speed up the game and make it more of a slugfest, which we all find very enjoyable. So why on earth would we bore ourselves out with land hate on each other? The one removal I have is to destroy Reliquary Tower usually, as a few people abuse the no max hand size rule to help swarm. Sure I could add more land into it, but I personally have no need. This list isn't concrete, however, so change it as you wish! It's not like there is a secret force to steal you away at night for not following this decklist to the letter!! Thanks for trying to help but just use that brain of yours a little more and we will all come out better! ;)

My girlfriend runs esper much the same way this deck is constructed and runs a total of 31 lands as I recall and it works FANTASTICALLY. The only thing she has issues with over coming my Sliver EDH and lets face it, 1v1 or group, that can be quite the challenge. I love this deck build. The only thing I would contemplate adding or changing is Thopter Assembly with Time Sieve for infinite turn combo as a back up plan and way out.

@MythrilJenova. Sounds like you have a girlfriend with the most fantastic taste! ;) But thank you for helping me say a low land count in this deck actually works, despite the apparent fears of others! As for the infinite combo, I have it listed as an option to other players, but I do not like infinite combos, seeing them as a cop-out victory, which is not as satisfying. That is just my opinion though! Thanks for your wonderful feedback; it is much appreciated!! :D

Very awesome deck! I recommend adding more lands though 30 is incredibly low for your curve. Theres only one card I can see that would be a great addition to your deckand that is Cavern of Souls, making your huge Sphinx un-counterable is huge!

Sweet Deck +1

After play testing your deck and half the time drawing one colorless land I really think its wise to play 3-5 more lands

903.9. If mana would be added to a player's mana pool of a color that isn't in the color identity of that player's commander, that amount of colorless mana is added to that player's mana pool instead.

Shouldn't this keep a deck like this from functioning well against red and green decks?

no, because you aren't adding red or green to your mana pool. You are spending white (Celestial Dawn ) or colorless/any color really (Mycosynth Lattice ) to play colors you couldn't normally. Otherwise, yes you don't really benefit from green/red players hands, other than stealing their land so you can produce colorless and they miss a land drop.

Oh, I didn't see those. I was just commenting on the commander.

Wouldn't No Mercy or Propaganda be better than Dissipation Field . With Dissipation Field you've basically invited anyone using creatures with ETB effects to take a swing at you.

@ender214. If they go to their hand, I can then cast them via my general. No Mercy would just feed reanimate, a common deck I play against. As for Propaganda , in EDH, 2 colorless mana becomes trivial the longer the game goes on. So that is why Dissipation Field is the clear winner!!

Currently running an Esper deck of my own with just under 40 lands and a few mana rocks and I find myself flooded sometimes. Still, isn't 30 a little light?

@ElCamino. Each person has their own balance. My playgroup loves lands, so it is easy for me to make up the difference with stealing and my mana rocks. Others may want more land. This deck isn't the holy grail perfect deck, just a tip based on what works for me. You can change the decklist to your style, there's no rule to stop you haha. For me, the land is fine, despite it looking dreadfully low. Playtest and find your own balance. :)

Didn't read through everything here, but I run Wash Out in my triplets deck. It's very helpful, especially since your playgroup doesn't use counters. You could also use something like Mortify if that's allowed in your group.

I'd like you're input on my updated Sen Triplets deck if you have the time. Thanks... +1 from me!

Esper, Party of Three...

I thought I would thank you for inspiring my Sen Triplets EDH deck Garage Sale I can't thank you enough for changing my opinion on artifacts and contributing to my favorite EDH deck that has caused worry among my playgroup. I upvoted this nearly a year ago and I feel I can't upvote it enough. Thanks for the Inspiration .

I proxied your deck and tried it out with my group. I simply love it! I had so much fun with it. We don't run infinite as well and I don't see why people have a problem with mana for this deck. I wouldn't change a thing in this deck and its quite fun. Thank you for posting this :D

@Thedudemansweet. Thank you so much for the kind words!! Glad you enjoyed this deck as much as I do :)

When I look at an EDH deck to give advice the very first thing I do is look at lands base. I am sorry, but I do agree with everyone else. It needs some work. There are 7 lands I would switch out.

Also 30 is too low for me. Your curve is just too high for that. If it was a 1-3 curve that would be fine, but yours is 3-7 (in my way of addressing the curve). I run esper as well. Mine is more counter control. If you are playing against competitive opponents your land is more important then you think.

Are playing in a pretty casual group? What are your rules on mulligans?

My land base is not perfect, but it is well balanced if you want to take a look at it. Wub Wub Deck

It is funny, because I was just reading Sen Triplets the other day... the deck looks amazing.

I'd consider cutting Dispatch , Dissipation Field , Unmake , Whispersilk Cloak , and Unburial Rites . I just feel that they're currently the weakest cards. You could replace them with more lands. Even with that many rocks, 30 is really low. As an example, my Karador, ETB Chieftain runs the least amount of land of any of my decks as it is packed full of more ramp and rocks than any of my decks, yet it still runs 34. Prahv, Spires of Order and Maze of Ith would be neat lands to run in here. If you find the room, I'd try to run Mortify , Swords to Plowshares , Righteous Aura , and Word of Command .

+1 from me.

Tezzeret would be so proud of you.

For this site, you don't need to list the commander in the mainboard. It is already added to the list as your General. Which gives you room for one more card. :D

I am building my own Sen triplets deck. it is my favorite card in the whole game.

Darksteel Ingot is better than Obelisk of Esper especially with Mycosynth Lattice on the field.
