I think this wording might fit better. The first and second sentence may seem (and could be) redundant but I wanted to limit this to final phase only. There may be counter impacts in the future that deal damage. Don't want this card to overpower them too. Also, with this wording, cards like phoenix radiation get to destroy their monsters.

[Cast Cost] [Pay 4 Gauge]

[Counter] "Counter Final!!" During your opponent's final phase, you may use this ability when your opponent casts an impact. If your opponent's impact would make your life 0, you may play this card. switch the target of the impact to your opponent instead. They receive all damage and effects as you would from the impact. (in case of damage reduction or specific card restrictions).

I personally think this would work better as a Katana Impact.

Secret Sword, Moonlight

[Cast Cost] Pay 3  gauge. When your opponent casts an  impact, if this card is in the soul of " Secret Sword, Lethal Formation ", and  If your opponent's impact would make your life 0,  you may cast it. (You may not cast it from your hand.)

[ Counter ]  switch the target of the impact to your opponent instead. They receive all damage and effects as you would from the impact.
