That's rough Shadai, but again congrats on making it to the top tier. Seems every year we see some different shenanigan brought from a local group. Reminded me of a recent steampunk themed mini's game I played at our local FLGS, dusted off my models went and played and remebered how much I dislike the, I move my whole crew then you move yours mechanic.
I've been thinking about how I would have played it. I know he had bodyguard but he would have grown impatient (maybe) if you just sat in your backfield and defensive stanced passed a couple rounds. Or maybe future tourney's will start having people save the bodyguard scheme till late so if they turtle up you can as well. Try to wait them out to show their hand first. It seems playing this way seriously undermines how the game is to be played to begin with.
