As long as Trinisphere is untapped, each spell that would cost less than three mana to play costs three mana to play. (Additional mana in the cost may be paid with any color of mana or colorless mana. For example, a spell that would cost to play costs to play instead.)

You're going to run Keruga, the Macrosage as the companion, correct?

What do you think about running the Trinisphere afterwards?

Alexplosio on Urza, Lord High Artificer is a dangerous man

1 week ago

If you're for some reason looking at this deck and thinking, "What on earth does this bad boy do?" well: here's the goal, kinda. You dig. and dig and dig and dig and search and search and search and search and ramp and ramp and ramp and ramp and by like turn 4 you've got infinite blue mana congradulations! The main win cons are: Painter's Servant / Grindstone infinite mana + Walking Ballista Mycosynth Lattice + Memnarch Urza's ability to cycle through your whole deck The main infinite mana routes are: Grand Architect + Pili-Pala Basalt Monolith + Power Artifact / Rings of Brighthearth Isochron Scepter + Dramatic Reversal + a way to get 3 nonland mana rocks cough Urza cough

Something to note is that the deck doesn't win immediately. It isn't aggro, it's control. You play cards such as Winters Orb, Trinisphere, and Static Orb to control your opponent's board(s) and then tap them down to allow yourself to not be controlled. The main weaknesses of this deck is artifact hate (duh) and Urza getting removed or negated. If you get Urza on board and he doesn't get removed, it is very typical to win in the next 2-4 turns solely due to your whole board being a mana rock. If cards such as Null Rod is played against you, it is important to remember that Urza taps your artifacts for mana, which is nice. On the flip side, if Urza is enchanted by a card such as Lignify, the reverse happens and most of your mana is unusable. In blue in general, once something hits the board it is very difficult to remove, so I included cards such as Pongify to deal with problems, but typically in my games I just outspeed the problem. I know I included a lot here, but I am still playing and tinkering with this deck. If you have any suggestions or comments or questions, let me know! I want to see more Urza players out there, and I think that he is a terribly fun commander. Also you WILL get targetted as hard if not harder than an Atraxa player, so good luck!

thitev on Manaless Dredge

The discard Pharaoh tricks and discarding dredgers with Unmask was new to me, so thanks for this guide! But I disagree on some points:

According to my calculation the likelihood of having at least one dredge card in the 7 card starting hand is

for 13 dredgers in deck: 1-(60-13)!(60-7)!/(60!(60-13-7)!)= 83,7%

for 14 dredgers in deck: 1-(60-14)!(60-7)!/(60!(60-14-7)!)= 86,1%

for 15 dredgers in deck: 1-(60-15)!(60-7)!/(60!(60-15-7)!)= 88,2%

So maybe you can get away with running only 13 dredgers ??

Also I think that Balustrade Spy (or Whirlpool Drake) is as good or better than Ashen Rider in almost all situations:

-fair blue matchups: winning anyway without Dread Return

-Stompy: if they have Trinisphere, no dread return anyway; if they dont have it and aggro us spy wins the game

-dark depths: spy = win

-show and tell: put spy into play; if we have Progenitus/Worldspine Wurm/... in deck we win. If Whirlpool Drake is used, those "shuffle back" cards are not needed, so no slot gets used up by it. If they put Progenitus into play, Ashen Rider doesn't kill it.

-Elephant Grass: Lotleth Giant doesn't care, spy wins

-Glacial Chasm: Ashen Rider is better unless the wincon is Thassa's Oracle

In all of these cases Balustrade Spy wins on the spot, not giving your opponent more turns to draw cards. Only drawback is you have to put a finisher like Lotleth Giant/Thassa's Oracle/Flame-Kin Zealot/... into your deck for the immediate kill, but without that you still get lots of Narcomoebas, zombies, etc and don't lose the game next turn as long as Progenitus is in deck or Golgari Thug is reanimated and sacced, so still enough time to attack with all the zombies.

psionictemplar on Sea-Green Tide (Simic Ponza)

I think you have a strong base here but the mana requirements seem hard to me. You start with green into double blue and then back into double green. I would recommend adding the 4th Breeding Pool and probably a couple more lands to boot. The Hinterland Harbor's in your maybeboard seem like a solid choice. Quite possibly the last thing you want to happen is to stall on lands while trying to stunt your opponents mana.

What I think could be a good addition to your deck is Garruk Wildspeaker. Casting as a 4 drop you could have him and bounce a land in the same turn.

The overall changes to your list that I would make are -1 Scavenging Ooze, -3 Cryptic Command, -1 Primal Command and -1 Trinisphere. In those slots add 3 lands and 3 garruk.

Daedalus19876 on Drawharmonicon | Yarok & Keruga

Yarok: You can't use Kinnan as the commander with Keruga as the companion. The commander counts as part of the deck, and Kinnan doesn't have CMC 3 or greater.

Enral: This seems like a hard deck to analyze -- I'd have to see it function to really understand how well it works with no low-CMC spells. I might look into Coalition Relic as a form of ramp, perhaps? But I very much like the thought put into ways to ameliorate the restriction, with free spells, split spells, et cetera. Are there any good spells with cost reductions that could work? Such as Avatar of Growth, Avatar of Woe, Curtains' Call, Mystical Dispute, or Price of Fame.

Trinisphere also seems like a MUST here. It doesn't affect you very much, while crippling your opponents.

@smilodex It's a downright shame the Mythos is Mardu, I was very much excited for it as well. Sadly, the little B pip in there makes it impossible :( Oh well...

Anyways: I think Timetwister is very optimal, but I lack the card too, so that makes it a bit awkward to test it out, especially since it's really expensive and I refuse to pay that much money for a piece of cardboard. Therefore, I'd like to put it there as the best in slot, but not really the most legit in slot. It might be worth it to play both Time Spiral and Echo of Eons alongside eachother to counteract the lack of twister.

I don't know if I like Wheel of Fortune too much, since we're trying to abuse our library with the Narset trigger. A Wheel effect could be good, but I think this would only work if we create an asymmetrical situation with something like Narset, Parter of Veils (on my list of cards to test). I do believe that these kinds of effects are very strong in our pile, since we get to cheat stuff out. Maybe a Windfall as budget option?

I do like the inclusion of a little staxy pieces. I myself am also testing out Teferi, Time Raveler in the list, as it provides a good way to cancel out interaction on our turns. Also trying out Narset Transcendent in order to max out tutor value and card selection when needed, coupled with removal.

As for Ponder and Preordain, that's a tough call really. I personally don't like Gamble a whole lot, since it very often reads "discard tutored card". Something like a Trinisphere maybe, but I can very much see the merits behind that card. It's pretty hard to choose and also very dependent on the pilot of the deck, I guess :)

I also see Jace, Wielder of Mysteries and I'm currently thinking that the card might be an excellent wincon. Especially with ETI and Omni. How's Aggravated Assault been in your list? What about JTMS and Dack? Really feeling this discussion!!

smilodex on Niv-Mizzet Parun Control cEDH

1 month ago

I mean i's your choice, but I dont know any 2or mroe-colored cEDH deck which is/should running as much basic lands as Niv does... It's really difficult to cast Niv Mizzest fast and because of that, I choosed to slow all my enemys down with: Blood Moon, Magus of the Moon, Back to Basics, Cursed Totem and Trinisphere, because those cards are fitting in no better deck...

New Cards I can recommend:

sake on Blue Fish Urza - cEDH Primer

1 month ago

Hi! Great list there, I've been using Urza as my main deck for a while as well and I have some questions:

  • Why include Thassa's Oracle instead of Jace, Wielder of Mysteries in this deck? As far as i understand, both will provide the win when we already have infinite mana and exile our deck with urza's ability. And I don't really buy the reasoning that oracle provide more utility compared to JWM outside the win. If I play oracle, it means I will only get to look at a few cards from my top without providing any actual card advantage. I will not play oracle early (talking about turn 0-4 here) especially if there is a fast combo deck in the pod since I have to hold up mana for interaction. It doesn't actually provide that great utility either in the middle to late game since you go -1 when casting this card, the scry from oracle is also kind of bad to combine with urza's ability since it shuffle, so if I see something important from the top of my deck, I need to have another way to draw it otherwise i have to wait to next turn to use it. And probably the only time I will cast oracle outside the combo is when I don't have anything else better to do. Yes, JWM cost higher than oracle and you don't want to have this in your opening hand or drawing it for like the first few turn of the game (but so does with oracle, so..). But in middle to late game JWM at least give you some utility in form of card repeated draw, which is pretty good for a long and grindy game when it happens. Also we kind of have a good blocker here in form of urza and enormous construct so I find myself sometimes able to ult JWM for +7 cards in hand. So in my opinion, JWM is still far better win outlet compared to oracle in this deck (oracle is kind of a dead card here, while JWM will be able to provide some value late game).

  • What is Steal Enchantment doing here? Is there is some specific card/strategy that you wish to counter by including this card?

  • What do you think about replacing Narset with a better stax piece for urza? maybe something like Storage Matrix? Since we are not running many wheel effects in this deck, I feel like sometimes Narset just act as a 3 mana cantrip twice (which is pretty good) but I don't see much synergy here for Narset. Wouldn't something like Storage Matrix or Trinisphere would synergize better with the rest of the deck stax pieces?

Thanks! :D
