if you want to use this card to destroy a shield, you have to give yours, i can't see any abuse in that( exept if you can give 1 level of your bone wall, this would be nasty)
immaterial shields and weapons should be protected against that, but even if they are not i don't think the card would be OP

Well, just 1 example would be to play the unupped "Shield" card then use this to replace the opponent's Dimensional Shield, or BoneWall, or Gravity Shield... etc.
Effectively, you can force the opponent to give up a shield which is at the core of their strategy and replace it with whatever crappy one you want from your own.
True, this requires giving up your own shield, but then you can always build your deck around that strategy.
Another very cruel trick would be to force them to take an upped Dispersion Shield... That could prove to be one of the most vicious forms of QC available yet!
Sure, they get to absorb a massive attack from you, but you just drained every last ounce of quanta they might use to counter whatever other nastiness you had in store for them.
Granted that would require a trio, but with a cost of 1
and 1
it makes a perfect combo to splash into a 'bow
