Results and Changes after the Showcase

So I learned a lot after the 10 matches of the Showcase.

I finished 6-4 but I kind of went offline after losing my first matchup against Rakdos since it was perfectly winnable and I threw both games. Side effect of running low on sleep, I had been up the last night looking into a lot more cards that can be implemented in the deck effectively.

List I played: https://www.moxfield.com/decks/pW8mGBK-nU-bk6aaGvUIqg

MUs:
2-1 UW Lotus Field (Impulse Version)
1-2 Boros Convoke w/ Thalia (First I hear Thalia being in Boros Convoke, it is a great card in the deck and really changes my sideboarding plans)
2-1 Lotus Combo
1-2 Grixis Phoenix (Really cool deck, didn't have any idea how to play against it)
2-1 Possibility Storm
2-0 5c Bring-to-Light
2-0 Geological Appraiser Combo
2-0 Yorion Fires
0-2 Rakdos Midrange (Heavy Misplay)
0-2 Rakdos Midrange (Played poorly as well)

So with that in mind:
Here is the updated version:

Sideboard Guide:

You will see that Azcanta and Dig Through Time are completely cut from the deck. This is mainly because I found that 4x Deluge is just enough to stabilize the game. A lot of times, Azcanta was win-more and Dig Through Time was sometimes awkward because I would have to exile my Deluge from my graveyard.

Shark Typhoon and another Lagoon Breach is added. Both are just very efficient cards and act as additional 2-for-1 type of cards that strengthens the overall resilience of the deck.

Sideboard:
Lantern of the Lost is completely cut as well as the one Temporary Lockdown. This allows the entry of 3 Strict Proctors and 2 Thought Distortion.

So the theory is that I never really missed Strict Proctors that much in the mainboard except in some matchups where you have to ultimately play greedier/faster, something that Proctor can allow. Therefore, I don't think there is a place for them in the mainboard still.

Tale's End is just much more versatile in the current meta and allows you to play a very regular UW playstyle without depending on Lotus Field at all.

However, with my Eureka! moment of finding out that Convoke now plays Thalia, Temporary Lockdown isn't as good enough anymore, especially on the draw. The main matchups where Proctor excels are:
Boros Convoke
MonoG
Fires of Invention
Elementals
Spirits
Phoenix (to some degree as it dodges Spell Pierce and replaces Tale's End).
Geological Appraiser Combo (although this matchup is already a bye)

Every other matchup not mentioned though, I do not like Proctor at all.
This includes:
Rakdos Midrange
Gruul Aggro
Rona Combo
GreaseFang
Lotus Combo
UW Control

As you can see, the matchups are quite split to the point that I still think Proctor is better in the sideboard, especially since there are a lot of matchups where you just want one Proctor and drawing two back-to-back is really detrimental. The deck still performs without it and is very strong.  This is mainly because Temporary Lockdown is also a very good card still, especially against Rakdos Sacrifice, a matchup that used to feel kind of bad without it.
