understand just by reading the card independent of any other unit in the game.

Worst offenders here are probably dove/angel or anything involving promote. It's a known problem but keeps getting shoved back in favor of more exciting things.

In terms of things that are a little confusing, a lot of these I view as double-edged where version A may confuse one group of people, while version B confuses the group that understood version A. There is also some hidden weirdness in the way that these descriptions are made, because some value is given to their ability to fit onto a certain number of lines of text, or avoid a single word taking an extra line, so things are rephrased multiple times in certain scenarios simply for that reason alone.

On note of augments, the reason the move type itself shows in the unit card is the same color/icon is shown when actually picking up and moving the unit, such as moving a royalguard and seeing purple squares everywhere, you can look to the side to see what that does without deviating into the augmentation description. Whether or not this is the most understandable way of doing things I'm not entirely sure, but that was the reasoning behind it, at the very least.
