So my friend and I were playing a game, and he was using a celestial knight, 3 spectral assassin's, and a shepherd of lost souls to attack my phoenixborn. I used my Beast Tamer's effect to remove 1 basic die and lower the attacking units attack by 1. He proceeded to play angelic rescue on his celestial knight to cancel the effect of my tamer. He said that my beast tamers effect targets, however the beast tamers card text doesn't specifically say "target".
So would angelic rescue work in this situation?
