Your write in is fine I think.Any suggested wording changes in my plans then (there IS a write-in option I've not filled, we really want to give Coil 0% chance of nothing anything wrong before going for him, or the timeline will dissipate and along with it our hostility towards him)? Or do we want to follow up on Armsmaster?
Regarding Coil, timeline thing is how he perceives his power. In reality he has Thinker power to retroactively make a correct choice, and then view what the consequences of the other choice would be. In other words, it does remarkably little if we just drop on top of him and take him out before he can act. This is a major weakness of Thinkers, as they need actions to make use of their insight so getting teleported on is a major weakness of theirs, something even Contessa can't escape.
At worst in one of his previous choices we attacked him so he has some prep, but realistically he doesn't have what it takes to prep for us correctly, with Scrying and Time Stop and everything. As an aside, we might also get access to some other capes through him, notably Noelle is a infinite source of capes we can give friendships bracelets to.
