[lore] Discard 1 Spell- and 1 Trap Card to target 1 face-up monster your opponent controls; Banish that target face-down. then both players must banish all copies of that card from their Decks face-down.

I got this idea based on that there is almost no cards that can return face-down banished cards. So this card could be used to easily eliminate (though not completely) a monster that is bothering you at a heavy cost (though I'm not sure the cost is right at the moment). However, it caries a risk when used against staples, as if you run them yourself, they go as well.

I think the lore is right, however I'm a bit uncertain about how balanced the card is.

What difference does it being banished face down make??

BFaDD doesn't grab it because you can't say it's a monster, even though this targets only monsters. And other stuff.

OT: Too high of a discard cost just to get rid of something. 2 cards, and they specifically have to be a Spell and a Trap, which should be useful.

Yeah, it basically stops anything trying to bring back banished monsters specifically.

I thought having a high cost would balance out the fact that you can use it to get rid of any kind of monster in addition to that its a quick-play spell.
My idea for the cost was also to make this a one-shot card, in that you can use 3, but other copies would most likely be used to increase the chance of drawing it in addition to pay for the cost should you draw 2 at once.

Though, I'm guessing it would be more cost appropriate to make the cost "Discard 2 cards"?
