As of late 2020, Adjusted Matrix is useful almost exclusively with Deus X. Which allow you to make any ice behave basically like a Bioroid (click to break). Unless Sandburg or Helheim Server is used, this will allow you to break any ices at the cost of clicks. Against high strength ices, it is a bargain. All this at the cost of 8 credits (still expensive).
Otherwise, with any other breaker, it allow you to interact with any ice on the board. Houdini and Engolo are very good for this. With that, you can still use only one breaker to break anything. It won't help much against Glacier, but it will help in a pinch. And it doesn't take any MU.
With it's high cost of 5 credits, it won't see much use. But with a cost of 2 influences, it can be used in any factions.
Note the flavor text, it describe exactly what the card does, all with a pretty image. Good design.
