If I play a strategy with an additional cost associated with it, like Reckless Rush, I still have to pay that additional cost correct if Ninja Tricks is played?
Will Ninja Trick negate the effect of straightening my personality?
Ninja Tricks
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.

Yes, and yes.
Note the difference between Ninja Tricks and Iron Will, the latter of which not only negates the action's effects but also allows you to ignore the costs.
And the straightening of your Personality is a delayed effect of Reckless Rush, so it would also be negated.
