Good Faith Rule: When an action is announced, the player must be able to target all required targets, meet all conditions of the action, and pay all mandatory costs, to the best of his or her knowledge.
Battle: If Tayoi is at a battlefield: Move her to another battlefield. Gain 1 Honor if Tayoi is attacking, or gain 2 Honor if she is now opposed.
I understand that an action can be taken even if effects will fail. However, this seems like a violation of Good faith even though the letter of the rule (and the explanation in the comprehensive rules) seems like it's technically not.
Example 1: I'm attacking with Tayoi, and Blanketed Forest is in play at her battlefield. My opponent in fact has another province I could theoretically move her to. I announce her action, which has no targets, one condition, and no costs. The condition is met. I attempt to move her to another battlefield. This effect fails. She's still attacking (let's say unopposed), so I gain 1 Honor.
Example 2: As Example 1, but my opponent only has 1 province, and no movement-prevention in play. Again, I announce, meet targeting (none) conditions (met) and costs (none). There is no "another" battlefield, but it's an effect and gleefully fail. The Honor gain isn't contingent on Tayoi's movement (which brings up a third question), so I again gain the Honor.
Example 3: My opponent has 2 provinces, and I attempt to move her to the other province. Opponent plays Hamstrung. Movement is negated, but as the Honor gain isn't contingent on her actually moving, I gain the Honor even though she stays put. (Similarly if I for whatever reason negate he movement myself just to gain the Honor).
Are all 3 of these situations correct (and valid uses of the action?) I'm essentially positive #3 works as I've described it, as well as #1. But in #2, there is no "another" province that I could move her to, but it's an effect, and actions don't need to have all of their effects succeed (yes, I've read the FAQ ). It just doesn't seem right though - though I'll gladly abuse it when I rebuild my Battle Maiden deck if that's the case
