So, Craw Wurm makes a sort of sense -- it's a wurm that just eats and eats --  but Craw Giant? I guess he eats and eats too, but he's pretty trim in that picture. It's an unusual pairing of word and imagery, and it only makes sense in a nostalgic, "look I made a reference!" sort of way.

That being said, for a mere one mana more, you get trample (that's good!) and rampage 2 (...). Of course, for a mere one mana less -- ie, the same as the original Craw Wurm -- you get this:

For one mana less, you get trample AND you get to drop rampage 2. That's two upgrades in my book. So, dear friends, that's how we killed both Craw Giant and Craw Wurm with a single slash of our vorpal blade, snicker-snack.
