Upped is practically a forced combo with silence really.
Effectively it becomes: Destroy 8 of your opponent's cards.
Its a good way to open up the hand for nightmare, but a little too powerful and heavy handed I think.
The unupgraded is good at least. May warrant a sligthly higher cost, even with the threat of card loss. Otherwise rush decks become just way to easy to power.
It does make a nice counter to nightmare (except for GhostMare variant)... at least in terms of freeing up space anyway. Also good to free up your hand in preparation for a fractal.
