So I took some damage (replacing Dreamgazer), equipped Arclyte Regalia (good ol’ Titan) and then hit the opposing general. I was surprised to take two damage and a charge to all my artifacts. So when Arclyte Regalia says “the first time your general takes damage each turn,” it really means it.
Compare playing spell - manaforger - spell - I’m 99% sure the second spell would be discounted.
