Based on this build by Youtuber KnightmareFrame but slightly edited. A Zaw with Exodia [Hunt] or Brave, high Stat Chance, and Viral is also recommended for this build.

To reexplain what is said in the video, Enemies frozen by the globe, when collided with something (terrain, another frozen enemy, etc) they take 50% TRUE damage which is flat and not affected by mods. True damage bypasses all protective measures, including armor and shields (but not Arbi drones), and directly hits their health. Apply that damage to an enemy with Viral procs on them, and they're very dead. the combination of [Khora]'s Ensnare and Exodia [Hunt] will make collision easier as they both bring enemies towards each other, you could also equip Exodia Brave if you think you do not need [Hunt] and so you could pick off the stragglers and get some energy from them. It is important to note that using [Nidus]' Larva instead will not work as the enemies will ragdoll, and will not collide with one another and therefore not dealing the true damage.

The build you see here is different because Knight most likely has other builds on their [Frost] that require different polarities to fit, whereas I started from scratch. I also replaced [Enemy Sense] with [Stretch] to give both Ensnare and Snow Globe more range.
