I might be a bit of a goofball for thinking this, but it seems odd to me that this creature has trample, but doesn't trigger on combat damage. Does this bother anyone else, or is it just me?

That's a good catch, jmg. My question is why does an antelope have trample? That made more sense when it was a rhino. What if it had "Untapped Plainswalk" and "Untapped Forestwalk"? Or at least the regular versions of those two.

You're both right, it seems odd. Maybe if it was flavored as a herd of antelope, then trample would make sense. Would Forestwalk + Plainswalk be too much for this cost, size, and rarity? Plainswalk might be a nice reference to Graceful Antelope... In fact, maybe I'll make it a 1/4.

This is starting to feel more like a rare than an uncommon...

An evasion creature with an attack trigger, but the stats of a defender? It doesn't sit right with me. Unless it had vigilance as well, which push it well into the Chinese menu rare category, which is difficult to make aesthetically pleasing.

It's quirky, but I like it.

I could see it at either uncommon or rare.

I think the GW "untap a forest or plains" is interesting whether or not it has any extra abilities. (In fact, it maybe should be GR, although I like the flavour of the current version.) There have been several "when this attacks, untap", but I'm not sure there was one this simple, and it would be perfect in an aggressive mana-heavy G/C deck.

Several of the other antelopes have defensive stats, and I thought it would be cute to mirror one of the few other plainswalkers. I guess it could also be 2/3.
