I thought I'd chuck in some of my thoughts i've got after testing out a Trick Room myself pretty extensively. Firstly, to those of you saying its "anti-weather", you aren't entirely wrong, its just that I have found Trick Room to be quite anti-meta. This metagame seem to be serving the speedier Pokemon a lot better than slow ones. Being able to turn your slow Pokemon into speedsters with just one ability is a godsend and can really rip shit up if your opponent doesnt know how to handle the situation they are in. Now obviously its sometimes difficult to fit Trick Rooms in when youre trying to also maintain the flow of the game. The above point is the first thing i'd like to comment on. I have found the 'sweet-spot' of Trick Roon users to be 3. With 3 users you have exactly a 50% chance to be able to use Trick Room precisely when you need it. The key to doing this is planning out what you are going to do per 5 turns of TR being up. Go in with a plan, execute the plan and ensure that when Trick Room runs our one of your users are in play and ready to set it up. Even one turn outside of TR can prove detrimental to your game. There is nothing worse than blasting that Salamence, only to have him live with a sliver of health, to go ahead with a Dragon Dance and sweep your team because you either dont have a priority user or because your team is just too slow to get a TR back up before being toasted. This leads me on to my second point. There are certain abilities and moves that are significantly nerfed when under Trick Room. One example being priority attacks. When you are almost guaranteed to outspeed all of your opponents team, why would you be worried about packing loads of priority moves that are weaker than ordinary moves? Of course, this is not to say you dont need to have one priority user, as I think its vital to pack a contingency plan for cleanup or sweeping without TR. My favourite thing however is by abusing TR, Pokemon that were before seemingly unusable suddenly become awesome. Rhyperior being one of my favourites at the minute. The thing is, Pokemon that are uber slow often have another stat pumped up in place of Speed, and this means under TR you are getting the best of worlds. Whether its your Slowbro outpacing that pesky Gliscor and OHKOing with Ice Beam, or your Rampardos smashing shit up with its ludicrous attack stat. Trick Room so obviously has its miscomings; Taunt ruins it, Trappers such as Dugtrio can be really annoying, trapping your weak TR setter and wasting it whilst your precious TR clock is ticking away, as well as almost total uselessness without TR up. However, with careful planning, good teambuilding, meticulous game plans and a decent metagame knowledge you can completely wreck those poor unsuspecting people. P.S. im just gunna post some of my favourite TR setters and abusers: Setters: Porygon-2, Slowbro, Dusclops, Reuniclus, Bronzong and Gardevoir. Abusers: Reuniclus, Conkeldurr, Marowak, Magnezone, Rampardos, Rhyperior, Scizor, Gallade, Crawdaunt, Breloom and Machamp.
