A player, 27 August 2008
yodin:"The player (or players) with the most personalities in play cannot bring a Personality into play if he or she has brought a personality into play this turn."
Skirt: "Recon Limited: Target a Scout you control, and bow him if he is not Ratling: Target a Province. After the next time you destroy the Province as the Attacker or win a battle at it, create two 1F/1C Ratling Creature Personalities"
1. So, Yodin essentially lets the player with the most personalities only bring one in per turn. How does this interact with Skirt the Edge, which gets you two peeps simultaneously? Assuming I've brought no other personalities into play this turn, would I get one Rat or two?
2. Last I heard, "winning a battle" changed meanings (per Standard Bearers) does this mean I can get free Rats off Skirt even if I don't destroy a Province or enemy units?

You would get two.
http://rules.l5r.com/Older_Card_Rulings_X-Z#Yodin_Sensei: "You may not bring a second Personality into play if the first you bring into play causes you to be tied for "the most" Personalities. [JA, 8 October 2000] However, this will not prevent multiple Personalities entering play simultaneously if you otherwise meet the conditions for bringing one into play. [ML, 08 June 2005]

Yes. All you have to do is have an army with greater a Force total than the enemy army's, which would be 0 if empty.
