Walking Ballista has been really good for me, it is mostly a tutorable removal spell that is also sometimes a finisher (especially great vs phantasmal image too). I have not tried Hangarback Walker yet but I do not think that it improves any matchups significally, it is probably great vs jund and other grindy decks but we are pretty well set up to beat these kind of decks already.
- Ghostly Prison: I have been playing martyr proc for a few years now and just recently dropped prisons from my list. It obviously shines vs creature decks which we are already mostly favoured against (still have wraths, paths, and of course martyr herself) and is absolutely terrible vs anything else (tron, control, combo etc.) So I think it is mostly a burden to have prison nowadays. I have only missed it vs dredge but dredge is not that popular lately.
- Cavern: I used to run a copy of cavern with wayfarer but i was not impressed. We already have proc and emeria (another reason to not play non plains) that are great vs counters so i dont think its needed.
- Surgical: I dont play surgical for budget reasons as its like 30 million tix so i dont know if its better or worse than RIP/ Relic.
I also recommend running the 1 of kami of false hope (I see a lot of lists who dont run it). I think its crucial to basically get a free martyr when you are on 5 mana with ranger of eos. It also helps with infect which is rising in popularity lately.
Feel free to ask any other questions as martyr is the only deck im halway competent of playing so i am happy to help new players out
