So I was thinking about the quality of life change that was introduced to 
Zilean's ult. I believe that they added the effect of changing the screen to Zilean's ult to clearly convey to the player that they were safe and that they could make choices that they wouldn't otherwise of done. Should 
Yorick receive the same change because his ult can also drastically cange a fight Or am I being a complete idiot and this is already implemented
A revenant receives a distinct spectral model. However, I do agree. A red tint to the screen would ensure that people know they have been revived and will react accordingly to their ten-second window of mayhem. Remember, clarity!
Unfortunately the other issue is that Riot is probably gunning to rework Yorick, so there may be a chance that they simply don't want to implement changes to his kit that may not make the cut post-rework. In other words, within time, Yorick may not even have a revenant. Only time will tell.
Speaking of time, you should prod Zilean for a few hints about Yorick's future.
