Post-game/Tempest Trial Builds

So I'm one of those players that likes to max out every unit on a particular save file. Engage, with its infinite skirmishes and relay trials serving as essentially a catch-all resource grind once you've got strong enough units to one turn the maps, has enough resources where its possible to max out every unit in the game, but it takes a bit longer than it did in past games like fates (I would compare it to the Echoes grind if anyone else was crazy enough to max out all units in that game).

Nevertheless, with Tempest Trials being this game's version of a "post-game" it is actually kind of fun to try and figure out what you should be running in the level 50 trials.

The Trials consist of 3 battles against enemies with scaling stats based on difficulty (level 50 being fully promoted units with capped stats in all but luck and a few other exceptions like strength on sages). This means that you need to use skills, rings, and weapon forges/engravings to gain an advantage over your opponents, as your stats will be near identical to that of your opponents in the same class.

I want to know what kind of builds people are running in these trials or any ideas for "no limit" builds, meaning assumed capped stats on a unit, no regard for how much sp the build would cost or how much gold would go into their weapons.

Full disclosure, I am crazy and want ideas since I've started to feel like Im just inheriting the same skills on every unit like dual assist+, Pair up, Vantage++, Speedtaker, Canter+ and want something either new, or just to see if those really are the skills that everyone is using. DLC is totally included especially since all of the DLC emblems have finally been added (spd/dex+5 seems pretty juicy for being +5 speed, +10 avoid, +10 hit and +2 crit all in one skill slot. But the basic stat-boosting skills seem to be unpopular so idk)
