Enduring Renewal não é uma opção boa pro deck?

Vitor, é realmente interessante. Vou dar uma estudada direitinho,mas é uma opção sólida.

Second Sunrise ?

cmsrDPM, Second Sunrise can be an option, but need some tests to know if it really would improve the deck. That leads to another question: what card to take off for it?

Beautiful deck. I have my own Teshar deck. A lot is similar, but I saw some interesting differences with you. I have the following questions about your deck building:

1. Why do you play Path to Exile instead of Swords to Plowshares? Do you want to keep the option open to ramp yourself or shuffle your library?

2. What is your experience with the Shimmer Myr and Emergence Zone cards? Do you really often use the flash effect?

3. I play Verge Rangers in my Teshardeck. I am fascinated by how this card synergizes with "eggs", Sensei's Divining Top, Millcards, Fetchlands, tutors, etc. The key effect of the card is "You may look at the top card of your library any time". What do you think of the card? Have you already tested the card?

4. Furthermore I play Heliod, Sun-Crowned in my Teshardeck. The card is a historic spell and Heliod, Sun-Crowned goes infinite with Walking Ballista. Otherwise, the card does little. I'm not sure if Heliod, Sun-Crowned is good enough. What do you think?

5. What is your experience with the Shriekhorn, Codex Shredder and Ghoulcaller's Bell? Sure, the effects are good. But are the effects really worth filling three card slots? I will try out the three cards myself and am curious to see how they will works.

6. I have seen the Banisher Priest card in several deck lists, but I have never tried it myself. Is the card that good? And if so why?

I would be happy if you would give me answers to my questions.

Thank you, valentin74!

1) Precisely for this reason. I chose to use responses that can also be used proactively. And Path can be used on some creature (an Ornithopter for example) to ramp off. Besides, it is quite common for Path to have no drawback (against 4C or 5C with greedy mana bases).

2) They are very useful in pods that I find difficult, with a lot of counter and interactions. Besides, they are necessary in situations where you combo off but your only payoffs are Urza's Bauble or Mishra's Bauble, where you can draw your deck on the opponent's upkeep and you need to win before giving a bigger window to stop you.

3) To be honest I never tried Verge Rangers because I found it slow. But if you are in a more midrange version, it may be a real option. Of course, before considering using it I would certainly use Mystic Forge.

4) I honestly don't like Heliod on this deck. Apart from triggering Teshar and possibly combo with Ballista, it adds absolutely nothing to our game plan. I prefer to use some redundancy from some of our combo pieces, or some way to dig more into the deck.

5) Not long ago I used only Codex Shredder and decided to test the other 2, and I really enjoyed it. Besides possibly answering opponents' top tutors, in practice, in our deck it is a "draw a card", since our graveyeard is an extension of the hand. In addition, it is possible to loop our non-artifact or non-creature spells with Codex Shredder.

6) Banisher Priest (or Fiend Hunter on some lists) is a necessary evil (like Leonin Relic-Warder). It is often an option to remove stax pieces that can harm our game a lot (Hello, Collector Ouphe and Drannith Magistrate), or even answer something that is essential to not lose before returning to our next turn (like Zur the Enchanter). Since we use many self mill effects, it is feasible to revive Banisher Priest with the Teshar effect, which is not the case with other types of responses. In addition, Banisher Priest can be fetched with Recruiter of the Guard.

Thank you very much for your detailed answers. I did a couple of test games with your deck and your Teshar-deck has won all my respect. Congratulations on this fantastic deck building! I quickly realized how strong Shimmer Myr, Emergence Zone, Shriekhorn, etc. are, which I was initially skeptical about. And indeed: Verge Rangers would be too slow on the deck. Too bad that Fiend Hunter has toughness 3. Creatures exiling permanently would be chic. One question remains: I saw the Claws of Gix card in other deck lists. What do you think of the card? I think, any-permanent-sacoutlet sounds pretty cool.

This activation cost never excited me to use it, although it opens up possibilities with Cathodion and positive mana rocks (in this case Sol Ring, Mana Crypt, Mana Vault, Grim Monolith, Mox Amber and Mox Opal. Only the first 3 make it possible to generate infinite mana in this case). I find it a bit limited and I prefer to use free sac outlets, but I confess I never tested it. If you do, then give me feedback! =)

I like your version of Teshar a lot. I confess, I hadn't much considered self-milling as a method of digging for my wincon, and my Teshar deck looks much closer to your maybeboard than your mainboard. One card I've noticed however that is absent from both is Aetherflux Reservoir. Something such as Teshar, Ancestor's Apostle//Thermal Navigator//Memnite//Scrap Trawler nets you infinite cast triggers, but ultimately gains you nothing. Aetherflux Reservoir turns zero gain infinite loops into an infinite damage storm combo. At 4 mana, its cost is a little high, but it might be worth including. Thoughts?

Alternatively if you prefer lower cost cards as your win conditions, I just realized you also don't have Altar of the Brood in the deck, which also would net you a win off the same combos as Aetherflux Reservoir, barring the presence of an Ulamog or some such anti-mill card.

xSindrix, in the first versions of this deck I was using Aetherflux Reservoir. But it was only minimally useful when it was already comboing. Although hypothetically I can do some loopings that lead to nothing and still win, it is still a corner case. In general, if you are going to use a payoff, there is usually something better that can be useful throughout the game (like the eggs). About Altar of the Brood, if the mill worked for us it was also an auto include. But the game of milling our opponents sometimes can be dangerous. There are more consistent and safer ways to win.

What are your thoughts on the two cards Heliod's Intervention and Brought Back?

valentin74, look at this: cEDH Teshar Corelist

I built this list making a comparison between the decklists that most stand out in Teshar's Discord.

Heliod's Intervention is a very good card. Of the lists, mine is the only one that doesn't use it, and just because my proposal is to play it all forward, so I insist that my answers can also be used proactively.

Brought Back, I don't think is so good, because in general what we sacrificed will actually return that shift, perhaps as a bad form of protection for Teshar. In the end, I don't see much of an advantage. Despite this, the DragonLordJippy list makes use of it.

*return that TURN

I made a budget Teshar deck centered more around artifact cost reduction rather than artifacts that net mana the turn they are played.

Teshar

A couple of the cards that you could make use from the deck are Scrapyard Recombiner and Ethersworn Canonist.

The first can search for Scrap Trawler and Cathodion (if you choose to also run it). The second is a realy good hate card stoping enemy combos and ensuring only one bit of interaction unless they use removal on it.

Canonist is really a staple on almost every list. But it is not the proposal of this list, since it is totally oriented to be proactive (even the removals). Scrapyard Recombiner is an interesting card, but I don't use it because it is too slow. The need to tap to search ends up being bad when you want to be fast. In addition, it is a very choreographed move and gives the opponents time to prepare properly. But despite this, it is feasible to use it if it is your personal taste.

What do you think about Phyrexian Revoker?

In a slower, more midrange, version, it's a good card for a well know meta.
