Is there a way to determine order of effects?

I'm just trying to figure this out. The game doesn't seem to have any rhyme or reason about what ability activates in what priority. I know that CAAs have an internal order.

For example, there is a Bojack "power to 1 for one turn", but if the opponent has a Great Priest, is Bojack going to make the opponents power 1, or 30,001?

Surprise Manuevers doesn't seem to activate against Defensive Stance / High Voltage as SM goes off before the buffs do (I've gotten murdered by this from JP players in ranked).

I would think that position within the deck would determine which abilities go when, but it certainly doesn't feel the case. It's like there is just this massive priority list and the game just follows it down. What am I missing?
