A player, 20 May 2008
Kaiu Shoichi 3F, 3C 5/5/2 Crab Clan * Samurai * Engineer * Siege
Reaction: After engaging, if Shoichi is in the current attacking army and it has fewer units than the opposing army: The Defender chooses units in his current army equal to the difference. Move them home.
Removing the advantage 0 Reaction: After engaging in a battle: Negate the effects of the first Terrain action or action on a Region any other player takes during this battle. Reaction: After engaging in a battle, if you control a unit at the current battlefield: Play a Terrain card as an additional Battle action.
Insurmountable Obstacle 0GC Terrain Battle: After each time an action moves a Personality home from this battlefield, dishonor him. You may take an additional Battle action after playing this Terrain.
Alight my question is this: I attack with Kaiu Shoichi, the other player defends with 4 guys. Both Removing the advantage and shoichi both trigger at the same time; "after engaging", so I chose order of resolution. So I trigger Removing to play Insurmountable Obstacle, then trigger shoichi to force the other player to move home 3 of his guys dishonoring each of them.
This right?

I think these are Words and Deeds cards, so you might want to check the sticky. We're not quite ready to answer questions on these yet.

That all looks correct.
