I got up to 4th on the ladder using an anti-meta team which included a set somebody posted earlier in this thread of Dragon Dance Ttar with weakness policy behind dual screens, it's kinda benefited by water attacks in that case as it can set up and if I was really worried it wouldn't take a hit dynamaxing was always an option to double it's health another time to get the weakness policy off, ditto usually has to wait for a lot of chip or reflect to go away to revenge and Grimmsnarl is an amazingly reliable screens setter.
I think it has it's place in the meta, checking most ghosts like Chandelure, Poltergeist, (non Focus Blast) Gengar & special Dragapult as well as most Hydreigon is a useful niche as there aren't a ton of options for that now and ghosts are becoming very common, just being a mon that can eat a hit and dish out a lot of damage is valuable at the moment. Also as HannibalLekter said there's always sand balance especially with Exca around.
