+2 x Scatter to the Winds and a confirming of suspicions would be good right?

I already get a crap load of card draw, so Confirm Suspicions to me seems redundant, especially at 5cmc.

Scatter to the Winds is almost an auto-include at this point for any control shell, but I felt that I didn't need it seeing as I'm running Censor and Broken Concentration, the latter of which because it has synergy with Geier Reach Sanitarium.

Even if you have 2 Geier Reach Sanitarium in your deck, i think you have more chance to use the scatter's alternative cost than the broken madness cost. In deed, you need 2 manas to activate your land and 4 manas for the madness cost, so you need a total of 7 lands (6 manas + the sanitarium) for this combo (+ 8th mana if you want create a drake token), then with just 6 manas and Scatter to the Winds you get a land-creature 3/3 so finally you need less mana.

If you want keep your broken concentration, you can cut for example just one broken and one renewed faith to add two scatters.

The biggest flaw of control decks in duels (and standard, now that the draw angle has been fixed) is the lack of good counterspells. Dissolve was barely ok, but Cancel is a bad card (and both scatter and broken concentration are 95% of the time just that). I sometimes wonder if the inclusion of Essence Scatter, unsubstantiate, and censor does not warrant MORE play of confirm suspicions rather than less, over horrible cards such as cancel.
I generally always slam shrivels and some cancel in my deck anyway so what do I know.

Geier Reach is bad imo, even with Drake Haven.

You're also only running 25 lands with no fixing or Hubs, along with BB costs, UU costs. You almost certainly need to fix your mana.

And Confirm Suspicions is not redundant at all with your card draw, because it also answers a threat.

I have never in my Magic Duels life paid the madness cost for Broken Concentration.

I have with baby Jace, which felt quite sexy.

so confirm is too pricey at 5cmc but you then say your plan is to madness out broken off of geier at 6cmc?

Back in SOI, I played a dimir control deck with jace, 3 call the Bloodline and 4 of the 3 mana cost looters. Sucked losing to curved out draws, but if opponent was just a bit slower, you were playing a Modern Control deck. Cryptic Command, doom blade, instant speed moan of the unhallowed + a lifelink squire, all that good stuff. What was funny was that, even though it was certainly not tier 1, it was perfectly viable to play.... The last few sets really upped the power curve alot.

I removed 3x Broken Concentration and 1x Renewed Faith.

Added 2x Scatter to the Winds and 2x Confirm Suspicions. I'm a little hesitant to remove any cards with cycling though, solely because they are my main win con in activating Drake Haven. Also Vert, without Geier Reach Sanitarium I wouldn't be able to get Haven off reliably. The card has over performed in this build so far.
