[mention]Jeremy4050[/mention], I think the major thing you're missing is Supreme Verdict. It's good removal for any creature deck, it's card advantage, it's almost completely unfair at instant speed with T3feri, and because it has such impact you can open a few other deck slots.
In those slots you might consider Unmoored Ego
for those lists that are difficult to interact with. Just name Valakut and take all 4 of them. In the past, I've gone EoT Cryptic for Bounce/Draw, untap on my turn and Ego something. It's not amazing card efficiency, but you basically just ruined their deck. Ego is strictly for those types of situations, but when it's useful it's amazingly useful. You can name Tron lands, even basic lands (why you would, I have no idea), or anything you need to be rid of. It goes well with Echoing Truth unless you're concerned about lands.
As for Colonnade vs Tar Pit, it blocks better. I personally knew I needed more White mana as well. I could see an argument for Tar Pits in a different situation, but being a good blocker in a real pinch is all I can really say apart from the mana colors.
[mention]aklepatzky[/mention], it's fine not to like Archmage's Charm. I was pretty cold to it when I first saw it, then after some games it really changed my mind; entirely up to you though.
I don't think 2 Field is too greedy. Especially if you're looking to fight Tron. It's less good against Valakut though. You can play Runed Halo
against Valakut, then you're just looking to protect the Halo. Or you can read my comments to Jeremy and try Unmoored Ego.
Fulminator... No idea. Try it, maybe you'll find an answer. It certainly does the thing you want it to.
T3feri is actually pretty good against Jund because it represents some card advantage, tempo, and prevents them from interacting on the stack. Also, Bloodbraid can no longer cast the cascaded card. Against everyone he stops any and all EoT plays from your opponent. There is no "on your draw step", no "before combat", none of it. If you don't find that useful, then don't play it.
If you want specific comments on your list:
- I'm not a fan of Thoughtseize in control. I've never been able to make it work or be comfortable with it. I would only use targeted discard against Control mirrors, and even then I have gone to using Thought Distortion out of the board to randomly win games.
- I think you have too many Snapcasters (same for Jeremy), they bring good flexibility but a mit full of them is not awesome. Think of it this way, Snapcaster adds 2cmc to every card it touches. Do you want to add four 3cmc Opts to your list? What about 6cmc Cryptics? I would err on the x2 side of them than the x4 side.
- Damnation vs Supreme Verdict? I just assume it's availability, but it could be a choice. I don't think there is much in the way of Regeneration going around, to be honest.
- I think Geist and Lyra are wrong here. Vendillion Clique probably fits better because it's got flash. If you're looking to dodge Valakut triggers, then Gearhulk is your bot,
At the end of this, your deck is your choice, and your meta is your meta. Both will help guide the creation of a final list that's different than others. These are just my opinions and my recommendations on my opinions. I recognize that I like playing some fairly off beat cards and lines, but I have had good experiences with them in the past; that's why I recommend them. I'm a fan of needing an effect and going to find it on gatherer then deciding if that card is cost efficiently enough to use. It's led me to Deepfire Elemental
, Curse of the Cabal
, March of the Machines
, and many more gems forgotten by mainstream players.
