If I banish two Djinn Prognosticator of Rituals for a Ritual Summon, does the opponent discard 2 cards when the Ritual Monster inflicts battle damage?!
You banish two Djinn Prognosticator of Rituals as materials for a Ritual Summon.
Yes. Each copy applies its effect, so when the Ritual Monster inflicts battle damage, the opponent discards 2 cards.
