How the deck wins

The plan is deck-out. Vivi's oshi skill, Rainy Day Vivi and 1st Vivi make the opponent draw, and in tests 36 of 53 wins came from their deck running out.

Su Debuts and 1sts make their center cost more to baton pass, so they get stuck. 1st Su hBP08-049 in the collab spot forces their Arts to hit the collab instead of your center.

2nd Vivi hBP09-069 takes 50 less Arts damage while they hold 7+ cards, and healing plus -10 mascots keep her standing.

For You with Lots of Love♪

Draw 1, heal 100.

Heal instead of losing holomem.

Don't use Vivi's SP. It shuffles both hands and all archived holomem and supports back into the decks, which undoes the deck-out plan.
