Just my personal sentinel build. You need to use [Helios] anyway if you're using the [Deconstructor], though if you're using the [Cryotra], bring the sentinel or MOA of your choice. [Synth Fiber] lets you pick up health orbs while at full health, which will heal your sentinel and also trigger Equilibirium and Arcane Pulse if you're running either of those. [Synth Deconstruct] will give you plenty of health orbs if you're using a sentinel weapon to apply status anyway.
