I think, considering it works on Battlecries, making the wording different would be a good idea. Something like "The next minion you play has no card text," which is in line with how Dragon Consort is worded (though manipulation of cost is very different to manipulation of card effect).
SIlence makes sense considering its official rulings text ("Removes the card text of the affected minion"), but different wording would make it more clear that it has an effect in the hand, too. For example, Knight of the Wild or Volcanic Drake would maybe not have their costs reduced if Purify is active.
Compared to the original purify, it has the following advantages:
Why would it silence battlecry?
"Hello. Would you like to destroy some evil today?"
I like the idea. 1 mana cost feels very cheap though.
Don't drink and draw.

That's actually worse.
