Those aren't staples, not every unit wants those skills. Galeforce, Copycat, Flamboyant are the closest things to staples, and even then, the support units don't want Galeforce or Flamboyant. Clear Mind effects are solely dependent on you using weapons that -2 Str/Mag, Skl on a regular basis. Weapons that aren't even necessarily the best. However, even then, if you get attacked by 5 guys on enemy phase with a silver weapon, that's still 5-6 turns of recovering to full power. Swallow Strike is a very good skill, but it's not extremely good in a game where most things happen on the enemy turn due to their larger numbers. Household cure is even less applicable as it requires you to use have a slot open for consumables. These are all great skills, but they are hardly staples for every character.
