Have you considered adding All is Dust with the New Legends rule. After testing out your deck. I found I can ramp very quickly, but a nice alternative reset might be beneficial. If anything I think the suggestion of 1-2 wishes would be helpful. Like having an evacuation and/or upheaval in your sideboard along with any other counters you may need. You can test out your other infinite combos with the Green Wish. The Black Wish is a rough choice.

Looking back over I realise that you have less lands that tap for multiple mana than I thought you did (only Ancient Tomb and Utopia Sprawl ). I suppose my suggestion was with the assumption that you would try to use Palinchron as a one card combo if you possibly could. Hence it would have been worth having more lands that tap for multiple mana (or at least that are probable to).

So then my question becomes is it really better to rely so heavily on Deadeye Navigator + Palinchron or would it be worth adding a few of those lands to give Palinchron the chance of comboing out by itself? I understand that you would need to generate 5 extra mana off these lands but it mightnt be too hard with coffers and cradle if you get the creatures and if you fetch more heavily for swamps (and/or if you put in some of the better 2 mana lands). You dont have too much tutor for these but you could add it and you already have Tolaria West at least. All this being said it would at least give you another option if navigator gets taken out, the infinite turn combo exists, sure, but it seems like a colossal pain in the arse.

If you do decide to add some other backup combo I agree that Living Wish would be great to find a replacement for Palinchron (Great Whale , Peregrine Drake ) you could search for cradle or coffers if navigator gets taken out (late game they might generate enough mana). Or search for a completely alternate combo (not sure which one would be best).

@crusificton: I like All Is Dust as a card, but it just feels too expensive. I already don't like overloading Cyclonic Rift . I'll keep it in the back of my mind as I play my next set of games, but I don't think it will make the cut.

@cooknathan: I would be inclined to add those lands if it weren't so difficult to get them going. I don't really want any lands that are ever useless, which is why I haven't included things like Temple of the False God . I used to be able to combo with just Palinchron when I could still play Primeval Titan and Cabal Coffers , but without Primeval Titan , Cabal Coffers is not viable. Gaea's Cradle is also kind of limited, and it will often be a dead card in the first few turns. For the sake of consistency, I can't make that gamble in the hopes of sometimes achieving a small bonus.

Living Wish into Peregrine Drake would be interesting. I need to think about the Wishes because they can offer a new depth of utility to the deck, but I'm not really convinced yet that they're completely worth pursuing.

Have you considered switching out Hinder for Spell Crumple since it replaces itself?

Also I know All Is Dust is pricey, but I recently played your deck in a 4 player game of avacyn, Slivers, and another control and I found that depending on Damnation of Cyclonic Rift wasn't super helpful. Surprisingly I had no tutors, but a large card advantage. I ended up taken out after ramping much faster than every other player.

Maybe Ixidron can be a solution? Cultural Exchange doesn't seem to work for this deck since there aren't enough creatures to merit it, and a player only needs to destroy one creature to nullify the spell.

With Living Wish you could take out someone like Teferi and move him to the sideboard.

Having Living Wish in the deck would allow you to move a number of your utility lands into the wishboard, which would allow you to switch out Chromatic Lantern for cheaper mana rocks and speed up the deck.

When you move something to the sideboard and use a wish to get it, that is the only way you can grab it. When it is in the deck you'd be able to tutor for it when it is needed. If you removed Teferi, Mage of Zhalfir from the mainboard and used Living Wish to go get it, that would be the only way to grab Teferi. If you left Teferi in, it would only cost 5 mana to cast Teferi, instead of the 7 with Living Wish + Teferi, Mage of Zhalfir .

@crusificton: Hinder is actually better for me because of cards like Snapcaster Mage and Eternal Witness . If I use Spell Crumple , it isn't as available to me should I need it again.

Ixidron is too slow and expensive to really be a solution to anything. I honestly don't find myself needing to answer board state all that often - I'm usually winning on turn 5 or 6, before other players really put anything on the field.

I don't want to put Teferi, Mage of Zhalfir in the sideboard because I often find him with Tooth and Nail . If Tooth and Nail isn't countered, but I know I don't have enough countermagic available to protect my combo, I will find Teferi, Mage of Zhalfir because he can't be countered off of Tooth and Nail . This gives me immediate and unanswerable protection for my combo.

@Blakkhand: You bring up a good point there. I don't often like seeing cards like Homeward Path or Boseiju, Who Shelters All . They're limited in application and not relevant most games. Boseiju, Who Shelters All is particularly situational because I only want it the turn before I combo (because it needs a turn to untap). Sooner than that is a hindrance.

So I was looking for a way to do infinite land untaps with this deck. It's probably there, I just can't seem to find it :-(. How do you untap riptide lab infinitely?

Ah shoot sorry I understand how. Silly me!

Iceberg ?
Little bit of blue ramp / EOT use of any loose mana. Little bit slow I suppose.

Iceberg is too expensive to cast and activate.

Pithing Needle and Rest in Peace and other cards that have a similar effect could be an issue for you? considering this is commander and only allowed "1-ofs"....have cards like this given you trouble before? Really curious, they deck looks amazing but at a glance I think it would be shut down fairly easily if someone was paying attention and expecting your Deadeye Navigator and such.

I've never encountered either Pithing Needle or Rest in Peace , and I probably won't. In competitive EDH, you really want to focus on getting your own combos down; pausing to put down a Rest in Peace or guess with Pithing Needle isn't something a lot of players do.

That said, those cards would be slightly annoying if they resolved. And if the did hit the field, I could answer them.

Most people don't expect the Deadeye Navigator unless they've played against me before. They won't even know I'm playing those cards until the turn I combo (although they may suspect I play Palinchron once I start the game by cracking a fetch for an ABUR dual to play Imperial Seal ).

Rest in Peace would really only show up if someone is playing the Rest in Peace + Helm of Obedience combo. That being said, Pithing Needle can be answered with Venser, Shaper Savant or Nature's Claim and such, so that shouldn't be a problem.

Test out Carpet of Flowers . If an opponent plays blue, free mana. If they don't then you win.

Have you run into Chains of Mephistopheles with your general yet? If Chains hits the board, it is tough times for Damia. Not sure if your meta even runs "two chains". Also, I actually lost a game with my Mono-B reanimator deck because of Necropotence and removed it due to liability of it...it got Faith's Fetters on it. There are several cards with similar effects (Angel of Jubilation only other one I can think of now that would affect Necropotence though). Competitive meta makes that one risky, have you encountered this?

There isn't really a lot of hate for Necropotence in the competitive meta, actually. Faith's Fetters is expensive, and Angel of Jubilation is expensive and limited.

I have also never encountered a Chains of Mephistopheles , but I should take the threat into account. Thank you for mentioning that one. I think the only real solution in my case is to counter it or remove it; there isn't really an easy way around it.

i thought that Chains of Mephistopheles was supposed have a nice chat with Nature's Claim (aka Nature's Claim destroys it)?...

Yes, but I need to have Nature's Claim in hand to deal with Chains of Mephistopheles if it resolves. If anyone plays Chains, I need to counter or destroy it if I want to recover.

Then again, Chains of Mephistopheles is kind of rare in EDH because it's extremely difficult to acquire and because it screws all players rather than just opponents. Its controller would need to use Necropotence to get around the effect and still have card advantage.

i personally wouldn't sweat it too much, how many times have you seen it previously, (not many i assume). if need be, you have thirteen ways to deal with it not including what other players do about it.

One of the things that worries me about the competitive meta is the number of solutions and threats that exist to everything. I don't have as extensive a playgroup as I really need, and that means my playtesting is kind of limited in what it can tell me about the deck.

are you able to do testing on cockatrice or anything of the sort? i find that those types of places are very useful. anyways, this deck will always (i'm sorry for saying this) have one weakness. on the plus side, chains is so rare that i personally don't think that it isn't too much of a problem. Final note, what is most likely going to go when you acquire any one of the cards in the maybeboard?

I'm not really sure whether the deck needs any of the cards in the maybeboard. I could go with Wish route, move the utility lands to the sideboard, cut Chromatic Lantern , and maybe add the Diabolic Intent , but I don't know whether that's the right move.

I feel as if the wish route would be too slow. Having to wish for a land you want or creature that is not in your deck isn't the most efficient especially if you can naturally draw it. when it comes to wishing for spells and creatures, you have to pay the mana for the wish and then pay the mana for whatever spell you want. In that case you aren't being efficient with your mana although you have the added utility of being able to wish for many different spells. It is something to consider though but I feel as if it isn't very good.

Why don't you try a big group game online?

You can do it through chat or something and work on your deck against a wider range.
