Night March is going to be rotated in a month or so, so I'd advise towards investing in Garbodor, now that Megaphone and Xerosic are out. Baby Yveltal + Yveltal-EX + Darkrai-EX could be a good idea (IIRC Yveltal-EX is, contrary to common sense, remaining in Standard, due to its recent Bacon Bird tin print, and if that's not the case, Lugia-EX can fill that gap).
Serperior/Ariados looks like a good idea, thanks to the speed provided by Forest of Giant Plants, but without Super Scoop Up & AZ, it can't reuse Servine's Ability, which greatly hinders its potential in terms of disruption, and this deck is one of the hardest-hit by Garbodor's new reign of terror, as it then loses Serpentine Strangle as well as all of Ariados' utility.
Vespiquen is going to drop a few tiers thanks to the loss of Battle Compressor, so don't bother trying to build a Bee deck.
Don't bother buying packs/boxes/tins/lots, as the ratio of useless to staple is worse than ever. N is the top dog in terms of Supporters, and the typical four-apiece of Trainer's Mail, VS Seeker, and Ultra Ball still applies.
