Your points about the importance of bolts and wasteland are good of course; I just don't think they make bolt and wasteland auto-inclusion in this deck (while they definitely are in tempo decks), especially if we have already great alternatives (Punishing fire).
I'm pretty sold about the cutting of Lightning bolts, while I'd really like to find some space for 3 Wastelands if I could.
My point is: while Bolts can be completely replaced by Fires without hurting too much our strategy, the absence of some form of land desctruction can hurt.
About the other topics:
- Pulse maindeck is not essential, yet sometimes it wins games... getting rid of a bunch of Goblins or Angels is pretty strong, and being so versatile also helps against a variety of permanents. However, I used to play it in the sideboard and I could remove it from maindeck again if needed, especially if I wanna find some place for Wasteland
- I don't get why first you ask the utility of the 4th Hymn, and then you say I'm light vs combo... it doesn't seem much coherent to me. The 4th Hymn is there to fight combo, since it's like the best card we can play against those kind of decks. I really don't understand how you can consider is unnecessary while you think I should play more cards to fight combo.
- the debate of Extirpate vs Surgical: when I play black and I have tons of mana / I'm not playing tempo, then I usually prefer Extirpate over Surgical. Since it usually come in vs combo, it seems to me that the uncounterability is pretty huge to be honest. For example, against a deck full of protection like Sneak attack, split second is a factor not to be ignored.
However, I can understand the reasoning behind the choice of playing Surgical (no tempo loss), it's just Extirpate fits my playstyle better.
- Loam: I don't use it for aggressive Wasteland strategies, but only to protect myself from opponent's Wasteland aggressive strategy. It comes in vs RUG and other mana denial decks like D&T and Pox. It's a silver bullet cause I can't afford more than one, yet it has solved some games when I saw it.
I don't consider it essential, so it can be sacrificed for something better if I find that something.
- Plague vs Jitte: I don't think they cover exactly the same role. Plague is there only for tribal matchups (and for D&T, naming humans), while Jitte would be pretty cute against aggressive decks like Burn or RUG.
It is true that they share of a lot of matchups where they would be both useful, but I simply prefer using the Ooze for life-gaining ability and Plague for tribal.
The other thing is: I don't like playing Jitte in a non-Stoneforge deck, since I can't abuse its potential.
Yet Jitte remains one of the best sideboard cards for this deck, so I fully understand people playing it; it's just another case (like Extirpate over Surgical) of playstyle preferences.
- light vs combo/graveyard decks.
To be honest, this is the only point where I don't agree at all.
In game 2-3, vs combo and/or graveyard I can play: 4 Thoughtseize + 3 Duress + 4 Hymns + 4 Liliana (15 discard spells/effects) + 2 Extirpate (anti-graveyard) + 3 Pyroblast (if playing vs Sneak attack / High tide): that means around 20 anti-combo cards, 1/3 of the deck!
And I'm not even counting the maindeck Shamans and Ooze, which are outstanding vs Graveyard decks.
Combo isn't and will never be an easy match-up for Jund, but I really don't see how I could be "heavier" than this.
