They probably will still be random, but will be persistent/hittable just like neco arc's, and the deer/crows will behave like nero's versions(won't disappear when you get hit and will be invulnerable).
To be honest I prefer it that way. If I don't know what I'm going to get next, neither will my opponent, and they'll have to hesitate to avoid jumping facefirst into a deer or a crow or a rocket NAC.
