Regarding the Rocket not working some of the time, here is what I have observed. Though this information is not final or conclusive.

Remember my Titan Rocket is on a weak alternate account, so I do not have that many instances that I can say for sure that the Rocket did not work.

Eventually, I noticed that when I have seen the rocket not work the following was also true. When the Rune Priest is out on the same lineup of 3 cards with the Rocket on another of the 3 cards, and the Rune Shield is on my same card that would be attacking the opposition card that has the Rocket Targeted on it, I have seen the Rocket not go off and my card have to destroy the targeted card via a regular attack. Granted my card did not take any damage, but in some cases had the Rocket gone off, it would have destroyed the opposition card giving me a free attack on the Mission (or Dual) points.

So, it appears to be an interaction between two artifacts affecting the same combat instance. With the Rune Shield effectively negating the Rocket. I do not have to the data to conclude that the Rune Shield blocks it 100% of the time though, I will need to observe more instances to make that conclusion. I do not know, if I have seen other instances without this combination when the Rocket did not work. It will take more observation on my part.

On a stronger deck with many artifacts, I wonder if there may be other possibilities of artifact interactions that might negate the Rockets effect. That might also include opposition cards artifacts.

Anyway that might give you something to look out for.
