Personally, I think that the charm is even better than counterspell the way the format is shaping out.
I can completely understand it's inclusion over the few copies of CS people play these days (1-2 if any), it can also come after 1 pierce slot to round out it's numbers in decks running 3-4 pierces on top of their counterspells. It effectively just adds 2cc removal to the deck without losing much in terms of cost, or protection.
