This [Limbo] build uses the largest bubble possible to lock down the map. It has very niche use cases. I do not recommend using this build in any mission where Nullifiers are present. We subsume a CC ability to pull enemies into the Cataclysm for even greater control of larger tilesets.

Ensnare is chosen because it has the large range and controllability for pulling enemies into the center of Cataclysm. Larva is faster but has less range and Resonator has more range but is harder to control without the augment. Banish is replaced because Cataclysm and Rift Surge keep enemies in the Rift but you can replace Rift Surge in operative defense.

[Rolling Guard] and Shield Gating combine to help you deal with priority targets outside the Rift.

Interception: This build is used to lock down most of the entire map, allowing you to [Protect] multiple points simultaneously.

Arcane Strike can be replaced with any offensive arcane of your choice to suit your playstyle.
