I would love to see the elf deck. How fun would it be to kill your opponent with 5 shaman of the pack

RtR seems costy in a deck like this.
Rallier gets back humans and/or your fetches.

I also love human tribal. I play an abzan version for cards like dark confidant.
Here's some cards I think would be good in Naya builds:
Burning-Tree Emissary: Free red or green mana to fill up field.
Lightning Mauler: Works great with Burning-Tree Emissary and Coco
Icatian Javelineers: This one isn't as good anymore but it can still intimidate some opponents from playing their 1 toughness creatures.
Renegade Rallier: This one I am unsure, it looks good but I have yet to test it in my deck.

If I were you I would focus more on wheel effects to make waste not the best as it can be and maybe add Liliana's Caress

The combo is still amazing for just dealing 40 to your opponent. Another thing you could do is mind over matter with Kozilek for infinite draw and damage.

This looks like a very cool idea. The thing I would do different I would run more things that get energy when attacking Glint-Sleeve Siphoner and Aethergeode Miner.

Maybe Create a clone deck of this and instead add cards you would want to run in this deck to see exactly what you are aiming for.

Fair enough, I might try this deck a few times see how it runs. If I will I will hit ya up with results.

I like this idea, If I were to change anything I would drop the 3 summoner's pact. I don't see them being good with the kiln fiend games. I think more gut shots, noxious revivals would be better and I would add one more Kiln Fiend for more consistant first hand draws
like say 10/60 16% to draw the needed cards in turn 1.

I would say add in avacyn in this just because how strong it is I might try a deck like this.

Pummeler is one of my favorite energy based cards other than brawler I was brewing around with an idea similar to this the other day.

I like the idea but I think ya need more token suppliers maybe Visionary Augmenter, Angel of Invention, Cultivator of Blades and/or Oviya Pashiri, Sage Lifecrafter?

Also this deck dies easily to field wipes so maybe add like selfless spirit to either main or side to protector your army.

I think you should focus on a lot more control like dropping Skyknights and Delver for maybe hard removal and maybe drop the combo since it really isn't that strong.

It's a burn deck he can win pretty fast on his own even if he runs out of cards he should win by then.
Just problem is if they side against him Game 2 he could get fucked hard.

I don't think he needs an atlernate win con but I would splash white for boros charm and lightning helix. And with white you can use that splash to put some enchantment/artifact hate cause if you get matched against a leyline of sanctity you are screwed

ThornCaster + Venom means Instant kills since Thorncaster allows them to do direct damage and deathtouch means any damage they do kills the creatures.
I would run 2 Thorncaster main board
I would also trade the Forbidden Orchards for Cavern of Souls since you don't really wanna give your opponent tokens for no reason.

I like Shambling over Angler because it's an 8 drop then Evolution can hit 10 drop creatures.

Slivers ideally want to be quick and annoying.
Running a lot of creatures is key and it faces your opponent with a lot of problems while answering a lot of your problems.

In your current build I would drop Door of Destinies, Primal Surge, and Birds of Paradise, and maybe sideboard Harmonic.
Adding a Gemhide Sliver in place of birds.

Next few cards are up to you to decide but here are some ideas:
Diffusion Sliver: really messes with your opponent's mana when they try to lightning bolt, abrupt decay, vapor snag, etc.
Essence Sliver: is good for life gain if against burn or just so you don't die
Virulent Sliver: Good against decks that have lots of life gain like soul sisters.
Megantic Sliver: Awesome buff card
Bonescythe Sliver: Gives Double Strike

Other cool cards that could work:
Collected Company: Search top 6 for 2 threats
Aether Vial: Instant speed slivers
Call to the Kindred: This one is okay but I prefer company or descendants' path
Mutavault: I don't run this but it is still a good card
Adaptive Automaton: Good if you don't want to splash another color for buff

Now Lands:
Sliver Hive is good and City of Brass is good but the others seem too slow, Here is some better ones.

Cavern of Souls: Comes out name slivers, counter spells no more
Reflecting Pool: This one is good with city of brass and what not
Ancient Ziggurat: More mana also works with reflecting pool.
Fetch Lands/Shock Lands: Fast but cost some life

Collected Company and Reflector Mage would be good in here

Landfall creatures could be interesting in this build maybe. Are you happen to be sticking to a certain budget?
