Another costs question... (L5R rules board)

A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing.

Ok, accordin to this:

"If the cost of an action or bringing a card into play is changed after the card or action has been announced, or if the payment of the cost was prevented, the player attempting to play the card or action may either allow the action or card to fail, or may use further resources to pay the altered costs. If the costs are not paid, the action or card has no effect. Costs already paid are not refunded. If the card was being played from the hand, it goes to the discard pile. If the failed action came from a card on the table, it still counts against any limits on use, such as 'once per turn'."

Lets say i use I KNow That Trick with 3 personalities in the battlefield, target a Randon Crab and and Hida Benjiro (Experienced) issues me a challenge and kill the initial target of my action. The rule allow me to choose a new target to dishonor and create the ranged attack( further resources). Does the same works with Guerrilla Tactics and Old Alliances??

Cards:

Title: Hida Benjiro (Experienced)

Text: Crab Clan Samurai • Yu 4 • Hero • Experienced • Unique

Reaction: After another player's action targets a Crab Clan Personality you control in Benjiro's location: Target a Personality the player controls. Benjiro challenges him to an unrefusable duel of Force

Title: I Know That Trick

Text: Battle: Target a Personality you control at the current battlefield: He produces a number of simultaneous Ranged 1 Attacks up to his Force.

Battle: Target and Dishonor a Personality you control at the current battlefield: He produces a Ranged Attack with a strength equal to his Force.

Title: Guerrilla Tactics

Text: Battle: Target, Dishonor, and permanently give the Shadowlands trait to an unbowed Personality you control at the current battlefield: He produces two consecutive Ranged Attacks with strengths equal to his Force and his Chi, in either order. If he is defending, bow him. Lose 3 Honor.

Title: Old Alliances

Text: Political Open: Bow one of your target Courtiers: Target a Personality. His controller may choose to dishonor him. If the target is now honorable, he cannot assign or move during the next Attack Phase this turn.

This is hard to interpret, since I Know That Trick has two abilities. I'm assuming you are referring to the first one, and that your opponent controls Hida Benjiro (Experienced).

If that's the case....

If you targeted your Personality, the cost is paid, regardless of whether the Personality is destroyed in the duel started by Hida Benjiro (Experienced), so the effects still happen. There is no need to try to pay again.

Lotus rules, pg. 44: "Destroying or otherwise removing a card from play after costs have been paid for an action on it does not negate that action’s effects."
