Doesn't matter what they do if the only thing you can do with them is play them at the same spots every time. They're either boring AF effects or super interesting ones, and either way I'm going to ask 'why are these on cards, and why did we lose an interesting mechanic in exchange for a bunch of utility we don't need?' I don't need exact tooltips to be able to say 'I think having a bunch of static tools are really boring'. Lustrate and excog are both healing tools on the same gauge, one is more interesting than the other. I still think aetherflow is boring. Is that something I need a media tour to tell me?
