First impressions of coop with two A20H StS1 players

I played my first coop run with a friend yesterday. It was definitely fun, but it somehow feels a bit jank/bolted on.

Even in single player, there is always going to be a balance between playing fast and playing well. With fast/uncoordinated team play, the gap is way bigger. We'd play pretty async. Our biggest repeated missed opportunity was one person attacking before the other applied Vulnerability. We could have planned the whole turn, or big chunks of it before playing cards. But then talking about the plan takes way longer than playing it.

I wish there was something like Monster Train 2's undo turn, but with stricter conditions. If you didn't get any randomness revealed (EG, card draw, randomly applied damage, white noise like random card generation), you can quickly/easily undo. So everyone could throw down a provisional non-random line quickly, and then you could undo/optimize it to get the cross character order better, without fundamentally cheating.

The played line becomes the communication mechanism, rather than verbalization.
