This is what it says in the help...

"Each turn, the players are randomized into a new move order. Each player's first order is executed in this random order, then each player's second order, and each player's third.

This means that you always have a 50% chance that your first order will happen before your opponents first order.

For the next round of attacks, the order is reversed so the last player in the first round gets the first move in the second round. It then reverses again for the third round, and so on. "

But if you look at this game, turns 2,3,4,5 I was chasing Khan round the board and he was getting first go each time, without playing any priority cards...

SO, is this a bug, or have I misunderstood?
