• Standard Procedure’s effect isn’t a copy effect. It becomes the chosen card until end of turn. Treat it just as though it were the chosen card. For example, say you chose Lightning Strike. That card is now Lightning Strike. After you cast it, it would go to your graveyard. If it got shuffled into your library, it would still be Lightning Strike. You could then find it while searching your library for a red card, for example. For all intents and purposes, it is the chosen card for the turn no matter what happens to it.2022-10-07
