Q: If a fighter from Spiteclaw’s Swarm is chosen by a ploy, but that fighter’s player uses Misdirection to change which fighter is chosen, which of the friendly fighters becomes Inspired?
A: Only the fighter chosen by Misdirection.
Q: If my opponent plays Confusion and chooses one of their fighter and one of my fighters, can I play Misdirection and choose a different pair of fighters (as long as one was theirs and one was mine)?
A: No. You could only use Misdirection to choose another friendly fighter (instead of the friendly fighter originally chosen by the ploy) that is also adjacent to the enemy fighter chosen by the ploy.
