Yep Victini will make the format even more interesting. Somewhat more luckbased, but certainly a lot more interesting. Buy your Sharpedos now!
Evolite will basically just make Zekrom better - it'll help Reshiram too, but I'm not sure how relevant the deck will be now that Zekrom has Tornadus and only hits itself for 20 and still gets up T1.
It will be interesting to see how much play Super Rod sees - most decks are running 6 or more attackers already and if they aren't they're running Vileplume. However, it could help Magnezone out seeing as it also helps its decking out problem.
N will be good, but Judge will see play as long as Yanmega sees play. This also makes Tropical Beach a lot more playable, which is bad.
Terrakion is way worse than Bouffalant. Bouffalant is good because you can drop it with a DCE out of nowhere as an automatic check to RDL for decks that don't have it. It also does some nice fast damage. Terrakion takes 2 energy and takes a specific type of energy, which automatically ruins it. I'll admit to it having better typing, but it's also twice as much of a scary start than Bouffalant. 4 retreat is horrible and a huge stalling liability.
The meta won't change much except that we'll get some gamble decks added to the mix and that the slower decks and decks in general get an interesting comeback aspect in the form of N, which should make for a lot of great games. But it's not like the meta needs fixing anyway.
N makes Lostgar more playable too, which should be an interesting deck if Vileplume and Gothitelle stay big. The Zekrom autoloss is a big problem though.
A card I think deserves some mention is Durant - it has a lot going for it now, between N, Twins and a lot of slower decks. The only bad matchup it really has is Zekrom and to an extent Vileplume (and timing out). Of course, any deck can beat it depending on each deck's start.
