There is no single right move

One real turn of Pokémon Champions VGC doubles in five steps: why the best play is often a mix of plans, and how Wisp finds it.

Turn 1 of a real Regulation M-C game: Basculegion and Kingambit against Excadrill and Tyranitar. Each of your two plans wins against one reply and loses to the other, so the best play is to mix them: plan 1 about two times in three keeps 60% whatever the opponent does. That balance is the Nash equilibrium, and it is what Wisp shows on every turn of your replays.
