Terminus seems like a good sweeper. The downside in Esper is that the benefit of Lingering Souls is dropping a bunch of tokens on the field. Terminus on tokens is pretty much a Wrath of God that doesn't actually kill creatures (e.g. you won't be exiling any Bridges from Below). If you have LS in hand or in the yard, then a Terminus for miracle is fantastic, because you can quickly recover. But since you have less control over when you can use the miracle, you might just be stuck with a brick for a while, even moreso than if it were Temporal Mastery. Mainly I'm just not sure there's space for it. Maybe instead of a Wrath or Explosives? I'm skeptical.
The downside of the miracles is, of course, the variance. With Brainstorm you can control that to some extent, but I think it's still a frustration.
The nice thing about Temporal Mastery is that it can be useful, or at worst, neutral, for not much investment at almost any time you see it after your initial 9. On the other hand, it's not as likely to turn a game completely around for you as a well-timed Entreat or Terminus would.
