The combination of Religious Talisman and Allegance Subverter is good, in that it doesn't ever miss, but it doesn't guarantee that you'll capture the target. They just don't always work.
The Cue Cappa in one of my games has Star Bases with massive Allegance Subverters. They only NEED one shot each... they have long range and do absurd amounts of "damage". I lost a bunch of ships the first time I hit a warp point defended by one... each AS captured one of my BCs, and that behemoth had a lot of them.
The Religious and Psychic trees make a nasty combination.
