I would like to submit an HO team for sample use as I think we could use one.

For those who have watched ZU rising stars and I guess my ZU Seasonal run this team should be very familiar. This team is one I have used quite extensively.
As for the sets:
Minior: Other than the Tera Dark that I'm running its a very common subsmash set. Tera Dark allows it to beat the bulky Mesprits that are seemingly omnipresent by negating Psychic Noise.
Vikavolt: EVs are basically to outspeed everything that is in the tier bar Jolteon. Modest is run because it allows you to beat Rest Snorlax, 3HKOing it after you get Throat Spray. Tera Poison is there for bulk and good synergy with Levitate, Iron Defense allows it to 1vs1 a good portion of physical attackers.
Bulky Veluza: The spread is simple enough speed so that a filet away allows you to outspeed all the non-scarfers, then the rest in physical bulk. This spread, paired with Recover alllows it to beat physical attackers with ease and sometimes means you can get two Filet Aways. Tera Fairy is the best defensive typing for Veluza to tera into, resisting the sucker punch revenge kill attempts.
Froslass: Common Spike Suicide lead with Taunt to beat Rocks Mesprit. Bulk over attack investment since Avalance is mostly there for the interaction with Destiny Bond.
Oricorio: Standard Offensive Spread with Covert Cloak(honestly for the sample boots might just be better, since its easier to pilot). Covert Cloak allows you to roost on Mesprit. It means beating Snorlax with Tera Fighting without running the risk of getting paralyzed by Body Slam.
Jolteon: Standard CM set with tera fairy Alluring Voice. Functions both a speed control and can make good use out of the holes Vikavolt and Oricorio can punch, or it can punch the holes for them to sweep.
