Not to sound biased, but it is probably the strongest card in a 12-post deck. It gains you insane amounts of life through Glimmerpost/Vesuva shenanigans and greatly accelerates the deck so you can play threats faster.

You might say that Crop Rotation does all that... what it doesn't do is provide you a tempo advantage because you never gain additional lands with Crop Rot, but you do with Primeval Titan.
I've tried playing PrimeTime, but kept cutting them for cheaper digging and tutoring. I find PrimeTime too clunky without running S&T, and I prefer to stay mono-green (and really more MUD-oriented at that). I can only reliably produce GG if I have a Candelabra in play, at which point I'd usually rather just cast All Is Dust and clear the board.

While Crop Rotation doesn't net you a land, the fact that it's an instant more than makes up for it. You can use it in response to a Wasteland, to blow out Dredge with Bojuka Bog, answer an attacker with Maze of Ith, surprise a Tendrils player with Glimmerpost, etc.
