@msg67183 jtms, tezzeret and some other walkers. However for your prisony build iam not sure how much the extra land they might get works against that.
I support having strip and wastes in there if you want to control the game by mana denial

I am not a dredge player at all, so take my opinion with a grain of salt.
For me this card seems to only work together with other direct damage or lifeloss effects to be enough (for example with the new golemn card that makes your opponent lose life equal to creatures in your GY). However, while I think that it is pretty potent to kill your opponent with direct damage/drain, there probably needs to be a good reason why playing this strategy over just attacking is worth it.

@volrathxp please make tme posts about these articles when they go up, it helps visibility a lot.

@volrathxp Just wanted to say, that i really enjoyed the article and iam glad the series is back. You manged to give a nice format overview without just highlighting the usual builds.

I would play so much Vintage if only I could. I just don't have the money to spend to get into mtgo. Whenever I hear people complaining about having to wait 10 minutes for a game I kind of think "man, I wish I had these problems", it's not like you have to stare at the window for the whole time, just do some work or other leasury things while waiting. But I guess that is kind of an outsiders perspective. The metagame atually seems very interesting to me. Most currently powerful deck have a very solid core, that allows for brewing around.
If you stay with the PO core you can play it from hard combo over kind of midrangy all the way to very controlling.
Same goes for Xerox. The core of the deck allows you to go for a very controlling deck with only JTMS and a mentor as your win con, over playing more snaps, pyros and even going very aggressive with delver if you want to.
Dredge has a ton of very flexible cards that all get supported by the very powerful and tight core.
Oath allows for multiple strategies, however it seems like the core takes slightly more cards and most options you can take revolve around what oath targets to run.

These are just some of the top decks, and these are just the most popular options. If you run an established archetype defined by a incredibly powerful core, it often allows for a lot of different cards and ways to utilize it.
Maybe my lack of playing on mtgo kind of clouds my perspective, since a lot of people are complaining that the metagame seems stale to them as if they would always play against the same 4 75s over and over again. That is not my experience at all.

Edit: iam sorry for the rambling, it's kind of late and iam tired.

A specific example of this card producing value was the following:
I was on Ritual Storm playing against Oath.
I cast a big must counter threat and my opponent has two options. His hand was force, Mission briefing, blue card and he had another force in his yard.
Option 1: play Force from hand and pitch blue card (or mission briefing)
Option 2: play Mission briefing to cast force from the yard and pitch his blue card, and still have a force in hand. Normally that doesn't sound so good, but the briefings surveil 2 made sure he would draw another blue card next turn to have his second force online.

It's not an insane play, and iam not sure how good the card actually is, but it definitely opens up new plays for a deck not really able to cast snaps, and produces marginal value. It is definitely playable, that's for sure, is it really good? No idea, needs more testing.

@protoaddct make this cost 1 mana and it would be great. At 2 mana i dont see a reason to play this over just drawing 2 cards with night's whipser.

@thecravenone Iam not sure if you are just mocking the fringe format or if you are actually interested.
It's a UB deck with rituals, petal, LED, a ton of cantrips, tutors like personal, mystical, merchant scroll and stuff like lim duls vault. For protection i have some cheap countermagic, discard (inquisition is obviously insane) and few removal.
It's all about finding Doomsday and either go the easy route: TOP Predict, Labman, unearth, BS, - BOT. Which is cheap and easy to pull off but can be disrupted by removal.
Or go for: TOP Ideas Unbound, Remand, Brain Freeze, -, - BOT
This storm kill is usually very hard to disrupt, but costs a ton of mana and you can't to be able to kill the same turn as casting Doomsday.
Of course all of those can be modified and the usual doomsday stuff. Sadly a lot of great cards like black tutors, yawgwill, Necrosis, fast mana etc. are banned.
It's really fun though I love when I get to play.

Well my Tiny Leaders Doomsday Deck has a new Commander finally...i dont really see it beeing playable in Vintage though

As someone who was very sceptical of the survival deck for a long time and credited a lot of its success to it mostly just being unexpected I have to say i was probably wrong on that one.
Glad to see another successful viable strategy.
