Defiant Trickster [Loki] Build

Update 31.2 buffed [Safeguard Switch] augment to give [Loki] 3s of invulnerability to himself in addition to providing 6s of invulnerability to allies (incl. Decoy). This duration is scalable with duration mods - so this build focuses on high duration to increase the invulnerability time for Loki (looking at ~9s of invulnerability duration) - add Archon shards to further increase the duration. Don't forget that [Safeguard Switch] also cleanses status on both [Loki] and allies.
PS: self invulnerability only activates on switching with an enemy or their corpse.
PPS: whilst invulnerable technically you're still being 'hit' but take no damage, therefore Arcane Avenger still procs making this build an easy way to upkeep +45% CC.

Why should you care about this augment buff? Well it's basically like [Rolling Guard] with x3 duration, with zero cooldown, and can be cast on any ally + yourself. No longer must [Loki] rely on only Invisibility to survive; stand in the face of any kind of bullet, explosive or blade and do one better than absorbing it like a tank - simply ignore it like a god.

Don't forget to cast it on your allies too to give them ~18s of invulnerability. Might be a little annoying for them but I'm sure they'll forgive you as you provide them with a x6 [Rolling Guard] effect.

2nd Arcane slot is flexible to your choosing but Arcane Avenger makes sense as explained earlier. I've subsumed [Excalibur]'s Radiant Blind for more CC options since its now high duration + high range; but really you can put anything here (or subsume none at all). Invisibility still has more utility than Radial Disarm here when you just need to fade into the background temporarily so I'd lose the 4 not the 2 (plus 2 gives stealth multi for melee).
