Let me try.

Secret Sword, Skill Breaker

[Cast Cost]Pay 3 gauge. When your opponent's monster's ability is activated, if this card is in the soul of "Secret Sword, Lethal Formation", you may cast it. (You may not cast it from your hand.)

[Counter] Deal 3 damage to your opponent! Nullify the ability by your opponent's monster and destroy it.

Rarity: Hmmmm... RR, I guess.

I apologies if i post anything against the rule or something.
