Now that I understand, LHK is right. Lyris, the player would know as if the mechanic is introduced in the game, then there would be a special counter to let the player know how long the materials are banished for. Unless, you do something with the Harmony monster instead. Something like you can banish it from the Extra Deck with the banished materials, but I'm just throwing ideas here.
