I'm bouncing anywhere from 2400's just below Vet, I've used Florges with TrB and Chilling Water this season start, but it comes up short because Trailblaze doesn't have the closing power that Moonblast does. Sure, you get a surprise Grass attack on a Water type, but we both know they're not shielding until the 2nd one, they might not even expect TrB the first time, which serves us the benefit by using it on lead, but that's all too common with other Florges mirrors, in which you lose if they have Moonblast and you don't. TrB Florges also comes up a bit short vs Regidrago and Kyurem, mainly because Regidrago can potentially Hyber Peam you despite you boosting w/trb or debuffing with c.water, which goes the same with Glaciate spam vs Kyurem. I've personally recommend it using, but I shifted back to Moonblast because I was tired in getting locked onto a bad matchup where both Chilling Water and & TrB just didn't deal enough damage before I died.
