Take it (1 DP) if you genuinely field Electro-Priests and want them to be more than a novelty. Nothing else in the faction supports them this directly, and the stratagem suite fixes their real problem, which was always arriving on your terms rather than the opponent's.
Be clear about two constraints before you commit. First, it is narrow: outside Corpuscarii and Fulgurites the detachment does approximately nothing, so if you own one box of priests this is not the pick. Second, the DATA-PSALM tag blocks the obvious combination. Data-Psalm Conclave is the other detachment that buffs Electro-Priests, and it also carries DATA-PSALM, so you can never stack the two. That is a deliberate design decision, and it is the single loudest criticism levelled at this detachment: the pairing everyone wanted is the pairing that is forbidden.
What it does pair with is any 2-DP core that says nothing about priests: Skitarii Hunter Cohort, Rad-Zone Corps, Cohort Cybernetica or Explorator Maniple. In those lists the priest block runs on its own detachment's tools while the core buffs a completely separate half of the army.
Sample gameplan: run a large Corpuscarii block in a Dunerider with a Tech-Priest carrying the Voltagheist Reliquary. Disembark and shoot into an objective-holder to cash Echoes of the Conduit Wars. Use Chant of Electrotraction on the turn you want to advance and still charge, and take the free D6\" from Momentum Feedback every time your priests are shot in the open. Keep the Fulgurites for the grinding fight where the post-combat heal actually accumulates.
