While on the field, the opponent cannot banish monsters, and it has an omni-negate once per turn while boosting its ATK

That is a good thing if you have an insect-based card to start off with

You can only use this effect of "Heavy Cavalry of the Indestructible Insects" once per turn

As for Vivis second effect, you may rest Vivi to give one of the opponents Characters a -2,000 Power reduction, and you can give the Rush keyword to a Character that doesnt have the When Attacking effect

There's a memory component here, but it's no harder to track than, say, the Day/Night cycle while there are no Daybound or Nightbound creatures in play
