Would you consider running Karn, Scion of Urza? It allows you to draw your deck like many of the Jaces!

Also, +1 for this great deck!

Nominae on Nicol Bolas, the party pooper

There are no tokens in my meta, and just some elfs in a Nissa, Vastwood Seer  Flip so I'm gonna drop Pyroclasm to the side for now, as well as Hypersonic Dragon for Preordain and Karn, Scion of Urza.

I'm gonna try to keep the Flame Slash for now as there's a lot of 4 health commanders in my meta, but I will surely try some games with Ponder

Thanks a lot !

Onyx77Thank you, having played a ton of the archetype I've grown very unimpressed with Koth of the Hammer. I think he's generally pretty terrible in most situations, I mean saying "oh he's like a big haste creature" is kind of wrong because he can't block and is easily killed on the swing-back. His board impact is very minimal, and you kind of want your threats to help stabilize the board. I understand he's a fast clock with his ultimate, but honestly in what world are you going to have your threat around for 3 turns and not be heavily favored to win the game? If you want to play him though I guess you can cut out the Pia and Kiran Nalaar? I really don't like doing that though because of how well they work with your mana rocks and Karn, Scion of Urza, and how nicely they stabilize your board. As for Goblin Rabblemaster, He's fine, if you feel you want to shore up your combo matchup (traditionally the hardest matchup) then you can run him in your sideboard but I've always used Trinisphere for that slot and now we have Damping Sphere which is more flexible and cheaper.

Cragon18 on Esper Tezzeret

I have been playing this UB Artifact build that could slot in Tezzeret pretty easily and could go esper with a tweak to the mana base. I enjoy the archetype overall but as others have mentioned it's fun but not necessarily well positioned. In my experience, artifact hate such as Stony Silence is not very common so there's that. Kolaghan's Command is still an thing and still a beating and any deck that runs it is likely a bad/unfavorable matchup.


Here is my list. It is kind of a mid-range artifact toolbox deck. I have "Homeless Tezzeret" (as described above) in the sideboard for extra removal and the ultimate (which is great and fairly easy to get) but you could easily add in Tezzeret, Agent of Bolas to the main or sideboard. The new M19 Tezzeret could be a good anti-control walker as well. I opted for Karn, Scion of Urza because of the card advantage and making 6/6-/7/7s is pretty good and the loyalty is really high making him hard to kill without multiple burn spells or an all out attack. I hope the list gives you some inspiration. Cheers!

Cragon18 on UB Improvise help

Hello fellow brewers! I have been playing around with an improvise deck for modern and finally acquired some of the key players (namely Karn, Scion of Urza) and built the deck. It is essentially an artifact toolbox deck that uses Whir of Invention to find the silver bullet artifacts (Ensnaring Bridge, Nihil Spellbomb, Pithing Needle) combined with early game removal/discard to control the board. It wins by -2 on Karn to make a 6/6-7/7 or a cheap Herald of Anguish that has been a house in nearly every matchup. I have had a good time with the deck so far and has done fairly well in a majority of matchups (I at least feel like I have the pieces to be in most games). That said, I'd love some feedback on the artifact choices and sideboard to help sure up the not-so-great matchups. Thanks in advance and happy brewing!


UrbanAnathema on Is Green tron still the ...

3 days ago

This is likely the most favorable meta Mono Green Tron has ever seen. I don't expect Alpine Moon to have much more of an impact on the deck than Damping Sphere did, which was minimal. Mono U has gotten a significant upgrade in Karn, Scion of Urza which gives it an additional card advantage engine while supplying relevant pressure and a wincon outside of Slaver lock. U Tron is on the upswing and it's definitely a solid competitive choice at present. That said, I think U Tron wouldn't be at parity or a superior choice to Mono G unless something unlikely happens like an Ancient Stirrings ban.

Thebiggalactus on Mr T's Artifice Master A for Artifact Team

you should add The Antiquities War, Tezzeret's Touch,Heart of Kiran, Herald of Anguish, and Karn, Scion of Urza if your willing to go all out. I would try to add more of the good vehicles, cause when they get turned into creatures they keep their keywords like flying but become 5/5s. The Antiquities War, and Tezzeret's Touch are ways to make your artifacts beefy. Heart of Kiran is the best vehicle hands down, and animating it will give you a 5/5 flying vigilance creature. Thats pretty damn good. Herald of Anguish is a natural fit with this deck and a controlling beater. Karn, Scion of Urza synergizes so well with this deck. He gives you cards, and he makes tokens that can get really big quickly. The only problem is that he's really expensive, and he's not so much a needed card, as much as he's a strong support card. cool deck, and I hope it works out for you.

garruk3 on The knight before rotation

6 days ago

I don't really see any reason to have Karn, Scion of Urza in this deck. You only have 4 artifacts in this deck, and 2 of them are The Immortal Sun. I know his first 2 abilities are pretty sweet, but I just don't see a use for him in a knight deck. Gallant Cavalry looks like it could work in this deck, getting 2 knights for four mana. Lena, Selfless Champion is also an option.
