I've been playing a lot of ranked Shadowverse since RoB dropped, I was around 25,000 before the patch, and I'm up to about 40,000 (AA1) now. D-shift was good for the first few days of the expansion, while everyone was still tuning their decks and trying to figure out what was good, but after awhile I started losing rank with it so since then I've switched mostly to playing Havencraft decks. Garuda Haven has been pretty good, Luxwing Reno is just a solid addition that can evolve and attack a follower while hitting your opponent's face for 2 damage in the process, and Valhallan General feels like an extra Garuda effect (+3 face damage on turn 6). Ancient Lion Spirit is just an excellent card, often becomes a 4-for-one or better against Daria.
Pre-RoB, I did most of my ranked climbing with an Elana/Seraph hybrid. I've found that post-RoB, Elana is probably the worst part of the lifegain deck: being able to just gain life puts you out of range of a lot of aggro decks, but spending turn 3 off to cast the amulet just leads to you getting out-tempo'd most of the time. Elana was at its best against lifegain decks like midrange sword, which seem to have mostly dried up after RoB, so now I'm just running Seraph. You beat most of the fast decks simply by gaining enough life to survive until the late game, and you beat most slow decks (like control blood) with the inevitability that Seraph offers, but things get a bit dicey against faster combo decks like Roach and Dshift that are capable of winning faster than you are with the right draw.
Overall my impressions of the post-RoB meta: I don't like it as much as I did before the patch. It feels like a lot of the best decks in the format are less interactive than before, midrange decks seem to have all but evaporated, and control decks seem to struggle when it comes to dealing with alternate wincons. (As a Seraph player, matchups like control blood just feel like freerolls to me most of the time; I will always be able to pack more Seraphs than they have Odins). Looking back on the pre-RoB meta, the most dominant decks were things like tempo forest and midrange sword, and I felt like those decks just offered way more decision trees, a lot of time the forest player would be looking at multiple options between slamming Cynthia, dropping Tia, or flooding the board with fairies and trying to play with Liza, while the new Roach deck seems much more linear. Sword used to be about grinding out incremental resource advantages by managing the board effectively, now it feels like it's just trying to survive until turn 9 when it can slam Albert and hit face for 10. I don't think that Daria is necessarily better than decks like PTP forest used to be, but it feels more frustrating to play against because it feels like a lot of the result comes down to the variance of their draws and whether they're able to chain Darias.
So yeah, I'm thinking of taking a bit of a break from Shadowverse.
Magic dropped a new set, and perhaps more significantly (or at least surprisingly), several new bans. The new "splinter twin" combo with Saheeli seems like the kind of thing that might also get banned after the PT with their new banning policy (which is apparently much more liberal), so I'm a bit loathe to spend money on standard cards for fear of the meta being shaken up too much. I'm in Pittsburgh and GP Pittsburgh is going to be taking place right after the Pro Tour so I'll probably break down and buy something like UR or UB control for that since they seem to be relatively cheap apart from the Gearhulks. (Or maybe I'll avoid the main event and just play side events all day.)
My modern deck (Infect) got hit by the Gitaxian Probe ban, so I'm waiting to see how the dust settles on that, but with the printing of Fatal Push I'm kinda tempted to try something like Esper or Grixis as I've always liked playing the blue control decks.
