Hello there,
[Atlas Prime], got another chance to blink, thanks to new Arcanes, some changes in game and last update that changed [Grendel]'s Nourish ability, which I used in this build.
Updated version strait from KnightmareFrame <- do check his video.
Gameplay:

Aura:
- Steel Charge - more melee damage and more capacity.
Exilus:
- NONE
or - Primed Sure Footed - up to you, actually it's personal preference.
Archon Shards:
- Crimson Archon Shards (RED): +25% (+37.5%) Melee Critical Damage, or +10% (+15%) Ability Strength
- Amber Archon Shards (YELLOW): any but Parkour Velocity, +25% (+37.5%) Casting Speed is always welcome
- Azure Archon Shards (BLUE): any but Shield Capacity
Arcanes:
- Avenger: +45% flat Critical Chance for 12s
- Molt Augmented: up to +60% Strength on kill, stack up to 250x
- Energize: Energy replenish on Energy Orb pickup, 15s cooldown
- Eruption: knockdown on Energy Orb pickup
- Blessing: On health pickup, +health, stack up to 50x
- Fury: On Critical Hit, +180% Melee Damage
Focus School:
- Naramon for its Power Spike
- Zenurik for Energy Replenish
- Madurai for its Power Transfer and Sling Strength
- Vazarin for its Protective Sling
Any other Focus School for whatever reason you want to achieve
Passive:
Lastly, some word about his Rubble Armor - Rubble restores Health to [Atlas] if he is injured, if [Atlas] is at Full Health, Rubble instead grants additional Armor that decays over time. The Bonus is capped at 1,500 points, and it decays at a rate of 5 Armor points per second, so if you want that bonus to stay with you... just combine Petrify and Landslide skills in battle.
Loadout:
Pay attention that melee weapons with specific mods affect Landslide damage (including RIVENS), but weapon stats do not. Also, after Duviri Paradox every Evolution on Incarnon weapon do counts!
Summary:
[Atlas] is created for one thing only... to smash, just like Hulk. And you are going to have much fun smashing enemies.
Enjoy!
