My personal Jund Control Deck I've put together with experimentation from the day 1 of Full Spoiler of Kaladesh to now.
It's got a 70% win rate, only having trouble against decks that are 20 counter spells, 10 draw spells, 5 planeswalkers/creatures. Not in those exact numbers but you get the idea.
The deck works towards keeping the board clear with plentiful removal, drawing some cards up and then using powerful cards like
Gonti, Lord of Luxury
for the attrition and deathtouch. This card can wreck players stumbling on lands or trying to draw their spells.
Goblin Dark-Dwellers for the recursion on the plethora of 3 cmc spells we have in the deck. Mainly for removal and some lifegain/recursion.
Scrapheap Scrounger
for the early aggro if needed and then a late game finisher as it gets around spot removal very easily with it's return ability.
Arborback Stomper for the late game life gain and having a trample threat to deal with chump blockers and put a fast clock on our opponent. By the time this card comes down, the opponent is usually under 10 life and only 2 attacks away from death, sometimes even a single swing.
Devour in Flames
is a card that has had a lot of great results for me. I've used it to completely clear out planeswalkers and have used it to kill 4+ toughness creatures such as Mindwrack Demon, Flipped Avacyn, Ishkanah after she's blocked something. But mostly to wipe planeswalkers from the field. The return a land to my hand isn't that much of an issue as if I'm looking to cast another spell and have either missed a land drop or don't have a land in hand to play, the bounced land that is tapped for mana is replayed to give me another untapped source of mana that turn.
There have been instances where I've cast
Devour in Flames
with 5 lands in play, followed up by replaying the Mountain I picked up and then casting Unlicensed Disintegration to clear their board of their creature and their planeswalkers, while dealing 3 damage to their life total occasionally.
Versatile lines of play is what this deck has given me countless times and the only times it comes up short is when there's mana flood or mana starve which rarely happens. I have yet to hit anywhere under 2nd place at FNM and coming in second place on Gameday, only losing out to Jeskai control, that had more than 12 counterspells in the deck.
Against B/G delirium I've had decent results. The only games I've lost against that deck are games where I've been mana flooded, drawing up to 5 turns in a row without anything in between. Aside from that, Aetherworks decks have been an interesting lot to deal with. There will be games where their hands are ripped apart with my transgress the mind on their marvels and Eldrazi they'll have in their hand. Harsh Scrutiny on turn 1 has been crippling when I've taken away their Servants.
The sideboard is what it is right now only because of my local meta. There is room for much more improvement in this aspect of the deck.
I only have the 1 Chandra and the 1 Nissa, I'm in the works of getting a Liliana, but I have not had any sort of situation where I've thought "Gosh I wish I had a Liliana right now".
Open to any suggestions and advice! This is a deck in progress, I want to have this deck win consistently enough to where I only have a couple upgrades once Aether Revolt comes out.
