We have a question if i use the ability of the Castle of the Swiftsword for negation of the Kaimestu-uo's formation. The the card will take effect attach a 0F Cavalry Naval Follower token to each Samurai you control at the current battlefield.Can I use the battle ability of the formation? Sorry to bother but there is confusing in my play group about this . We only need to clarify it .
This is the new wording of the formation from the oracle of the void
Kaimetsu-uo's Formation After this card enters play: Create and attach one 0F Cavalry • Naval Follower to each of your Samurai Personalities at this battlefield. While you meet the conditions to put this card into play, you have the ability, "Battle: Any number of times per turn, target a Personality without Followers that this ability has not targeted this turn: Bow him." Battle: If you control three Samurai at the current battlefield, each with an Item or Follower: Put this card into play there. Discard your other Formations. You may take an additional Battle action.
Thanks to whom will answer this topic.

I'm not sure what you mean about "negation"; none of the cards you mention negate anything.
However, I hope I can help by telling you that if you use Castle of the Swift Sword to use the Battle ability on Kaimetsu-uo's Formation from your hand, you will NOT get the Followers from the trait.
If that wasn't what you were asking, sorry, and please try again with a follow-up.
