So Force of Vigor is obviously a really good card and it allows us to go completely away from mana, but then Leyline of the Void becomes a big problem as there are only 4 solutions in the deck rather than 8-10 as I generally prefer.
The main deck's primary threat is losing to Wasteland. Noxious Revival seemed like a great solution to Wasteland and sort of decent against Leyline in that it pitches to Force of Vigor. I may go back down that route.
Gitaxian Probe seemed highly suspect to me at first.
As I thought and thought about how to find Force of Vigor more reliably I contemplated adding mana back in.
Chain of Vapor could pitch to the counterspells which is decent.
Then there was a game where I probed into Vigor. That seemed good. Then I thought about adding more free cyclers.
In particular I contemplated adding 4 Mishra's Bauble, 4 Urza's Bauble and 4 Street Wraith.
Against a Leyline each cycle speeds you up by 1/3 a turn. By the time you are 12 cards deep you may find 3 cycles which means you are 15 cards deep. If you found an extra cycler then 16 cards deep. It is a lot more likely to find Force of Vigor by then.
Testing around with this a bit I first found that this makes the Force cards way worse since none of the new cards to pitch to anything.
I also found that the deck becomes a lot faster. It is very common to get 2-3 extra dredges by turn 2.
The deck also becomes far more resilient to Wasteland. For instance if I have 2 Baubles on turn 1 and you waste my Bazaar I can still get 3 dredges on turn 3. This is not as good as Noxious Revival at all but still not bad.
Turn 2 Ichorid which chains into a bunch of other stuff is far more likely if you are dredging several times before your second turn starts. Noxious Revival can't do this.
Note that the Baubles give valuable information about your opponent's current and future hand and make it
more likely to hit with your first Cabal Therapy.
Finally post board when 17/60 cards cycle for free it all of sudden becomes a lot more likely to find that Force of Vigor against Leyline of the Void
Lets say you are on the play post board and your opponent drops Leyline.
You have 2 cycles in your opening hand so you cycle twice.
Then you play and activate Bazaar. This draws you a 3rd cycler so you cycle a 3rd time.
You are now a full turn ahead of where you would be without the cycles. On average you do not quite get 2 non Bazaar cycles in your opening hand, but you average more than 1.
My testing was done assuming opponents were boarding out their countermagic. This may not be optimal. I have been of the opinion that non Mental Misstep countermagic is sub optimal post board. The role of the Leyline is not turn the other deck into a prison deck, but instead to act as a road block to let the other deck combo out first. Now that there are only 4 Leyline removal spells in the whole deck, the whole prison strategy becomes a lot better.
You cannot cut dredgers below 12 because you really want to dredge and not draw pre-board.
I pulled out Chalice of the Void because it seemed bad with 8 Baubles, but I can just drop the Baubles first. When I don't have a dredger I might draw into a Bauble but a dead Bauble is not the end of the world because Bazaar.
Probably Chalice belongs.
The Unmasks in the board were in case of Jailer or a similar creature. I was thinking about using them on the play only, but I did not use them much at all.
I would consider all of the other usual suspects including Noxious Revival, Misdirection, Hollow One, Contagion, Spinning Darkness, Ravenous Trap and Dakmoor Salvage. Losing to Wasteland when I boarded out the Baubles was a problem so I am currently leaning towards Noxious Revival.
If your opponent does not have Leyline then you can bring in the Forces and remove some of cycle cards so you can counter hate spells.
