Spirit of the Ring
Long story short, Stellarknight Delteros activates its effect and I don't get any chance to activate mine to protect Felgrand Knight, so my monster gets destroyed no questions asked. Why?
hmm you should get chance to activate it.....
unless delteros is summoned by using star seraph scepter, then scepter effect will trigger when delteros
xyz is summoned (as delteros effect), and due to delteros effect you cant respond to it
