I had assumed, based on the Fish examples we've seen, that "Gift a [creature type]" was shorthand for "opponent makes a 1/1 vanilla creature of the named type". But here the Octopus is an 8/8. Do the Comprehensive Rules have to list power and toughness individually for each creature type that can be gifted?
Edit: and color too I guess. Maybe abilities, if in some future set it becomes possible to gift birds. Hey, I just got a great idea for a Twelve Days of Christmas-themed Magic set.
Edit 2: this raises an interesting question about how Artificial Evolution interacts with the Gift mechanic. One way to look at it is that you already promised a certain gift when you announced the spell, and AE would come too late to matter.
