The old joke is that if you put a $10 bill into every pack of Magic cards, players would complain about the way it was folded.
Now, I don't know the truth of this, but there is certainly a tendency for the vocal minority to be, well, vocal about issues they don't like. Last year that was Slivers. Specifically, the fact that Slivers looked different in the art than the old slivers, which basically all looked like the same angry alien bug.
Well, if you're one of the people who were really bothered by that (There are actual dozens of you, I'm sure), we've got you covered.
Here you go! Angry alien bug Slivers are back!
I'm sure this was actually a conscious decision on Wizards' part. They tried to bring back a fan favorite last year, changed the art because they also changed the core Sliver mechanic ("All Slivers") in order to conform with new design standards. It didn't go over well, to say the least. This was put right on top of the list (over, say, reprinting $100 fetchlands), and now we have the result: Angry Bugs Are Back!
By the way, this card is awesome and sure-to-be a casual favorite.
