Last bullet makes it pretty much a more generic Dark Bribe, albeit as a spell speed 2 xD
Oh, also it won't destroy the card, relevant when negating monster effects, Fields, Pendulum scales, or Cont. Spell/Traps. On the other hand, you can force the opponent to trigger your cards that activate when they are destroyed, discarded, etc. The discard even sounds dangerous in DWs, which will get to apply their additional discard effects. Can't tell if it's too good or not, even as a Normal Trap. You can always get a couple of cards in the GY to be banished and prevent giving the opponent a plus.
