Mirran Crusader needs a big mention in the Melira POD matchup, as that's the main reason many are mainboarding it now. It tends to just end the game very quickly against Melira POD.
Good sideboard cards against Scapeshift:
Leyline of Sanctity
Runed Halo (naming Valakut, the molten pinnacle)
Fulminator Mage
Liliana of the Veil
Burrenton Forge-Tender (Protection against red sweepers)
Aven Mindcensor
Tectonic Edge
Good sideboard cards against GR Tron:
Stony Silence
Fulminator Mage
Aven Mindcensor
Tectonic Edge
Ghost Quarter
Burrenton Forge-Tender (Protection against red sweepers)
Pithing Needle or Oblivion Ring against Karn.
Good sideboard cards against Storm:
Rest in Peace
Leyline of Sanctity
Runed Halo (naming Grapeshot)
Liliana of the Veil (reducing their hand is important)
Zealous Persecution (killing goblin swarm)
Also Rule of Law, Ethersworn Canonist etc., but I don't think we need that narrow cards when we have so many other good answers.
Bogles:
Runed Halo (usually naming bogle or the hexporoof elf)
Liliana of the Veil (or other cards with an edict effect)
Mirran Crusader
Zealous Persecution (on the play you can sweep their 1/1 hexproof creature in response to an aura spell)
Enchantment removal like Disenchant or Oblivion Ring

His list looks similar to a list that 5-0'd the MTGO Competitive league recently:

The idea of Splicer/Resto in modern jeskai is not new. Look up Shohei Mita's version that top8'ed GP Kobe some years back, also with 2 maindeck planeswalkers (Elspeth, Knight-Errant was the best option at that time)

I Guess Bruna, Light of Alabaster can beat Hexproof auras if it gets to block or attack and take over all auras on the battlefield hehe. They do play Rest in peace, though, and may have protection from creatures. A black creature with an edict effect is an alternative, but then there is the leyline..
EDIT: Leyline even stops Gifts ungiven itself, I found out.
Used to do that with boremandos. The surprise factor can definitely win some games.
Elesh Norn is a way to beat a difficult matchup dredge (and other go wide strategies, affinity, tokens etc. ), and it combines nicely with our new tech Secure the Wastes Wurmcoil Engine is a potential target in these Jund times. Iona can beat some strategies, like Storm, mono black, burn (might be too slow)Green-Red Scapeshift etc.
Is there a creature to beat Auras?
Just came to remember how Todd Stevens on Jeskai Jace crushed Brad Nelson on Bloodbraid Jund 4-1 in this matchup test from before the unbanning:

Most were convinced jeskai was the better place to be in that matchup at that time. But you find it to be super rough?

With an uptick of grindy decks with Jace, Bloodbraid Elf and Liliana of the Veil, Settle the Wreckage feels very strong. Very strong topdeck and it works with snapcaster in the lategame. Even at just 4 mana, 3 tokens at instant speed in their endstep is a strong play in many situations. And if you have time, you wait until it's a game ender. This deck often get to a high number of lands, and it's good to have a card that really can take advantage of that.
Wall of Omens is pretty nice against the Bloodbraid elves and snapcasters that are everywhere.
3 path? Hmm, that's a bit risky isn't it?
https://www.mtggoldfish.com/deck/944882#paper
He added one land, up to 19 lands. I'd still think the mana would be a problem quite often. The cascades looks quite inconsistent, or at least tricky, like cascading into Death's Shadow when you're at the wrong life total, or cascading into traverse when you don't have delirium.

EDIT: Interesting to see that IoK's inability to take away Jace came up against UW Control
The affinity player sacrificing Champion to LotV is not a very common scenario, as he most often have other weenies he can sacrifice, or he can activate a blinkmoth/Inkmoth to sacrifice. LotV can work against affinity sometimes, though, especially if they have a slow hand.
According to Reid Duke's sideboard guide from june all 4 LotV comes out against Affinity:
https://www.channelfireball.com/articles/modern-jund-deck-guide/
How good LotV will be depends a lot on the meta you're playing in. LotV is bad against swarm decks (Affinity ++), dredge, and bad against lingering souls, recurring creatures like Kitchen Finks/Voice of Resurgence, Blood Ghast, Flamewake Phoenix etc. LotV is generally good against most control and combo decks, and good against decks with few but powerful and non-recurring creatures. Most jund-players prefer 4 maindeck LotV, but some jund-players have had great success with 3 LotV. Examples - Keita Kawasaki, who top 8'ed Grand Prix Guangzhou 2016 with 3 LotV, Vidianto Wijaya in Grand Prix Los Angeles 2016, and Andrew Huska who 2nd placed Grand Prix Minneapolis 2014. The 3-drop spot in Jund have been getting more competition over the years, with Kol. Command printed in 2015 and LotLH in 2016 to compete with LotV. I can also mention Ben Friedman's controversial new BBE-list with no LotV and 2 goyf:
http://www.starcitygames.com/article/36629_The-End-Of-Moderns-Golden-Age.html I don't think his list looks good, but it demonstrates that there are different opinions of these things.
I did say lategame. As we all know, delirium is not for certain, but with Lilianas, brutality etc. there's a high chance even a regular BGx midrange deck will reach delirium at some point in the game (probably later than in a dedicated delirium deck like Traverse shadow of course) In all cases it can be played as a basic land, so it's not a dead card if you don't have delirium. Some prefer the opportunity of lategame value to the increased chance of flooding when you go from 24 to 25 lands. We do play goyf, so every measure to increase the chance of delirium, like adding brutality, seal of fire, Nihil Spellbomb etc. can also help goyf.
A couple of example top 8 lists with Traverse as a one of:
http://www.mtgtop8.com/event?e=12554&d=272444&f=MO
http://www.mtgtop8.com/event?e=15847&d=297303&f=MO
Pro Tour Return to Ravnica (Seattle) is a very interesting event to look at where jund was the dominating deck. Deathrite had just been printed, so a lot of players still ran the classic 25 lands 4 BBE lists without deathrite, and the players who had picked up deathrite played 24 lands. The 25 lands lists usually ran 6 manlands and Treetop village was more popular than Raging Ravine.
Many of the decklists are listed here:
http://mtgtop8.com/event?e=3652&d=221861&f=MO
Most of these lists played 3-4 Kitchen Finks, like Willy Edel (who made top 8):
4 Blackcleave Cliffs
2 Blood Crypt
1 Forest
1 Misty Rainforest
1 Overgrown Tomb
2 Raging Ravine
1 Stomping Ground
2 Swamp
4 Treetop Village
3 Twilight Mire

2 Ancient Grudge
1 Batterskull
1 Bituminous Blast

And some lists even played Geralf's Messenger in the 3 drop-spot instead of Kitchen Finks, like Bruno da Fonseca:
4 Blackcleave Cliffs
2 Blood Crypt
1 Forest
1 Lavaclaw Reaches
1 Marsh Flats

Actually, Brad Nelson played horribly that match. He practically gave away his Thrun and lotv. And Todd's deck was loaded with high value 4-drops. Which is great against jund, but probably not very playable against the rest of the field..
