This armored elephant appears in both Magic 2010 and Magic 2011, with different flavor text:
In its original printing, it appears to have been engaged in the defense of a city, but once it's in the hands of General Avitora (instead of some nameless Mastodon keeper) it's attacking someone defended by walls. Which might remind you of a different piece of flavor text.
So ... what card in Magic 2011 shows a flying armored elephant?
(Okay, so the armored elephant on Mighty Leap doesn't have its tusks cut off. Close enough!)
