Also encountered this when I played Lightborn Cariel followed by Lord Barov. Expected the Silverhand Recruits on the board to be 3/3, but they were 3/1 instead.
Lightborn Cariel’s effect is contiuous, while Lord Barov’s effect is a one-shot, so Cariel’s effect should have priority (apply after Barov’s effect).

I also recall using Goru the Mightree in the past and getting the expected results, unlike Cariel.
