(Only card text pertinent to the questions is shown.) Open Emotion Open: Choose your performing unbowed Samurai and show a Strategy in your hand: Once this turn, after engaging in a battle as the Defender, you may take an additional action to play a card with the shown card's title.
Sneak Attack Reaction: After engaging: The Attacker has the first opportunity to take a Battle action or pass during this battle. Play then proceeds in turn order from him.
Reinforce the Gates Reaction: After a player announces a Battle action before the Defender’s first normal opportunity to act or pass: Its effects do not happen.
-----------------------------------
1) Does Open emotion allow the defending player to play the shown strategy before the attacker can react with sneak attack? I think the answer is yes, because the delayed effect triggers before reactions.
2) Can Reinforce the Gates be used to negate the card strategy played by open emotions ability? I think yes because it qualifies as an action taken before the defenders first chance to act.
3) Can one play multiple copies of Open Emotion to then play multiple cards before the chance to Sneak Attack? If yes, do they have to be cards with different titles?
