On Evolve - Put a Carbuncle's Sparkle token into your EX area. Give each Carbuncle's Sparkle in your EX area "This card costs 2 less to play."
QIf my opponent has a Rulenye, Omen of Silence on the field and I evolve 2 copies of Carbuncle, Immortal Jewel, can I play the copies of Carbuncle's Sparkle in my EX area for 0?
AYes, you can.
QIf I evolve 2 copies of Carbuncle, Immortal Jewel, do copies of Carbuncle's Sparkle in my EX area gain "This card costs 2 less to play" twice?
AYes, that's correct. In that case, they would cost 4 less to play.
