Which would you fast TM?

Golem or the hur drag

I would say Dnite since it's still one of the strongest attackers in the game...but maybe wait until you get a Ttar in case you don't like its fast move. In this meta, it's probably best to focus on your strongest attackers for raids and gym takedowns.

The Rhydon or 96% Dnite imo; they have the most to gain from the switch. Golem would. E pretty good too.

i'd go with the Golem, very useful against fire types, specially against Charizard. I have a lvl38 B/SE Tyranitar but i kept using my lvl30 R/SE Golem instead.

How common are Geodudes in your area. I have a few high level high IV Golems that could use TMs, but it seems blasphemous to use a TM on something so common while you have rarer mons waiting. Rhydon and Flareon seem like the same problem.

Either Sw/Hu or Sw/Dp Dragonite would benefit a lot from a quick TM.

I'd go w golem. Is one of the most useful Pokémon in raids now and in the future (for all the legendary birds).

Golem. RT/SE will be the top supreme counters to a lot of the legendary birds.

If you don't already have a double-Dragon dragonite, definitely the 96% sw/dp. Next choice would be Golem if you don't have the double rock version. The Sw/Hu dragonite is not a terrible third choice; the result will be excellent against grass.
