have you considered Bower Passage it pretty much makes your creatures unblock able.

HydraOoze,
Looks fine, I need to test this card. Thanks for suggestion :)

I run this very same deck but I cut Nicol Bolas Pw and mained Mirari's Wake. It synergizes well with the deck overall

nayaman,
Thanks for advice, sounds quite good and I'll try it immediately

Have you considered sliding Kaliaa in this beast? I don't know if this would water down your deck but, ya know, free dragons...

Is there a reason that you prefer Ur-Dragon as commander over Scion? Seems less explosive and harder to protect.

jeffbriem,
The Ur-Dragon is less dangerous as a commander so I usually don't need to play archenemy from the beginning. Also I'd like to cast my flying beasts so Eminence comes as a blessing, that's why this deck has many land ramp spells and Quicksilver Amulet to cheat in a Dragon from time to time.
Another point is that Scion is one-shoting enemies but one at the time and is too combo oriented for me. Original Ur can win through explosions of Dragons combined with Dragon Tempest and/or Scourge of Valkas abilities and that's the reason to run Dragons like Dragon Broodmother or Utvara Hellkite - you basically win with army of almighty beasts from sky :D

Vlasiax thanks for responding. I can see the thought behind it as avoiding Aggro. I guess my meta just looks at the combo decks as a bigger threat and leave me be until I can bring the dragon out. But if you like longer games with an army of dragons, a permanent cost reduction makes sense. It’s go wide dragons rather than a single explosive dragon. I’m not sure that I’m converted, but I do see the argument.

No problem I'll gladly answer any of your questions. However for now I'm not making any changes to this deck unless there are any new Dragons that will really have an impact (M19 might be good place to print something powerful)

Your lands are much more versatile than mine. I decided to go for the noncombat damage win as well as combat damage. More enchantments that work like Sarkhan's Unsealing like Where Ancients Tread and Warstorm Surge. More cost less cards like the Dragon servants. That's just me. I do admire the setup and would like to see our Dragon decks match up.

LordD_Chaos I used to run servants but they're too risky because boardwipe not only clears your creatures - it also takes out your ramp. Where Ancients Tread and other cards like these are just too costly to make it worth and because of high cost I cut Mirari's Wake.

Vlasiax I use mana rocks early so I can afford to run the 5 and 6 cmc enchantments. Especially if I can get a Savage Ventmaw out turn four, right after a Fervor. That's probably why I only have a 34% competitive rating but my whole play group fears it more than my other decks.

Using such enchaments and Utvara Hellkite can kill some people just by declaring attacks.

Mana Echoes + Savage Ventmaw + Hellkite Charger + Utvara Hellkite equals infinite combat phases if they don't have a response. May take a minute to setup but Tooth and Nail + Wild Pair helps. (Tapped out said that first syngery combo coudlnt be found)

Well, that depends on how you want to play your deck - I'd like to cast 5-6 CMC Dragons instead and to get more consistency on getting damage win-cons I run 2 black tutors as extra copies of e.g. Dragon Tempest. It might just come down to one's preference but I'd like to just cast low CMC support/ramp and higher CMC Dragons with powerful effects.

Also to get infinite combat phases you can just use Aggravated Assault + Savage Ventmaw combo, seems to be more reliable as needs only 2 cards instead of 3-4. But if you're not planning on getting tutors since they are quite pricey then your suggestions are quite good budget-friendly options :)

I chose Hellkite Charger over Aggravated Assault to "try" and have more creatures than enchantments. The smaller enchantments like Temur Ascendancy make sure the 5-6cmc dragons, casted on turn 4, really count.

It OK, us Ur dragons players cant rely on Tappedout's ave cmc number, cuz we gots dem eminence >

majorappliance, you can alter cost of cards using *CMC:X* command, where X is your defined mana cost of a card and your Dragons now can be displayed with "proper" CMC

ooh, can you also have the thingy ignore your commander cmc too? because it does and thats annoying

majorappliance well sure, just type 0 instead of it's original CMC but I don't do that just because I sometimes cast it to get that attack trigger effect.

well, its still not part of the deck, lol, so unless you shuffle it in, also, even if its set to zero, the math is still slightly wrong because the tappedout calculator will still make it divisible by 100 cards (example) instead of 99, so if i do the math, my deck is 2.53, but tappedout will calculate 2.48 because the dividing number is incorrect, oh wells... im just ocd about numbers...

majorappliance, then I'd add the amount CMC of commander to correct the displayed numbers. However, this isn't as important as the CMC of the 99 cards, where you need to find more balance - in The Ur-Dragon 's case 4+ CMC slots are mostly occupied by Dragons so 0-3 CMC I'd use for cheap Dragons (there are only few of them "worthy" as of now), ramp and card draw.

Right now I'm trying to make this deck a little more interactive - do you have any ideas what cards to add and which might be underperforming?

ive played dragons since ur dragon existed, and modified the precon to get to what its at, its not my main, so i havent spent too much time on it as i could have, but big swinging dragons is always satisfying. i think dragonlord kologan is a bit weak, since its just a 5 drop that gives haste, does the other ability happen?, in terms of utility, its not all that, you can always run a Hall of the Bandit Lord if you want another haste enabler. The dash kologan also doesnt do a whole lot, other than being an earlier cast, if its to get that commander damage in, i would recommend a Kessig Wolf Run . its nice with the ramping a dragons deck has to do anyway. How has the nesting dragon been for you? I dont run any fetches, so it really underperformed when i tried it out, i really wish i could keep it, but no fetch is no value for me. I really stick to tribal themes, so if it isnt a dragon, i dont run it. Meta is important with tribal decks, pods these days dont run as much board wipes in my area, so maybe i can get away with more nonsense. if you havent seen my deck already, ill just link it Vanilla Dragons, its not top tier, but it wins more than it should

majorappliance,
Dragonlord Kolaghan is a Dragon that gives Haste and that's it, nobody should bother reading anymore from that card but it's a Dragon so every synergy counts and does great job here.

Hall of the Bandit Lord looks tempting but in my mana base I try to stick to colored sources of mana so this and paying 3 life is too much for me.

Kolaghan, the Storm's Fury scales (no pun intended) really well - for example 3 Dragons attacking means +3/+0 for everything so it only gets bigger with every creature. I used to neglect this but tried her back with Dromoka, the Eternal and they are functionaly the same.

With commander damage I probably won like... 1 game? It is possible with Fat, Scaly Pricks and Kolaghan, the Storm's Fury to punch someone out but it's quite unlikely since I'm trying to win with infinite combat phases or damage from Scourge of Valkas and/or Dragon Tempest and take down the whole table.

Nesting Dragon is amazing, especially with Vaevictis Asmadi, the Dire but you need fetchlands to really unleash its true potential just like with any other landfall card: Lotus Cobra is a good example.

I used to try "only Dragon creatures" but EDHRec definition of tribal is easier to utilize and gives some room to experiment: "Decks are considered tribal if they have more than 10 creatures and at least 60% of them share a tribe." so I decided to throw in some mana dorks to speed up my game and have something to do during early turns. Also Goreclaw, Terror of Qal Sisma is amazing here because with her most Dragons' cost falls to 2-4 instead of normal 4-6 with Ur-Dragon's Eminence ability.

independently, we seem to have arrived at very similar builds (which is no small feat for this commander, as it can be tweaked and piloted in many different ways, tailored to different metas, and as playstyles either treat the commander as essential to cast or a side bonus for the late game, if/when it ever happens).

so. i'd be curious, if you have the time and inclination, to hear what you think about the list i'm running currently.

http://tappedout.net/mtg-decks/03-04-19-the-ur-dragon/

the only apparent major changes aside from a few cards in your list that i don't run that aren't as good when one isn't running a full suite of fetches (i only have the khans fetches) is to include the greater good/patriarch's bidding/crucible of fire package, so that the sac'ing can dig deeper and net larger raw card advantage. but maybe that's too magical christmasland?

have you tested those cards? and any thoughts about whether/not the 36 land count is correct/the ramp package is sufficient enough to be consistent?

really happy to see there's a contingent of ur-dragon fans who are still trying to optimize a list for higher power casual/casual-competitive!
