Was just playing Arena, I played a Battle of Bywater against an opponent, they played Orim's Chant and it meant that Battle of Bywater didn't resolve even though in the rulings of Orim's Chant it specifically says “Orim's Chant won't affect spells that your opponents cast before you cast Orim's Chant, including any spells that are still on the stack. Orim's Chant also won't stop your opponents from casting spells after you cast Orim's Chant but before Orim's Chant resolves.”
