Tough. I really just wanted to have the creature be a 5/1, and have the activated ability grant trample. That's more for common, though. I don't think I've seen this ability play out quite like this... though I assume there must be some Maro for creature tokens out there.

I don't really see what's red about this. It would have been nice in RtR block as a Selesnya creature, but I don't know if it fits in Aer.

To be honest, I don't see a real need for the center activated ability to be Red, Green and White. I mean, I agree that it shouldn't be contrary to those colors' philopsophies. But it's not like cards like Drowned were poor flavor-wise, because blue has nothing to do with regeneration. At least, that's my take on it.

So, yeah, green likes token creatures, and so does white. Red... I'd probably call it third when it comes to token creatures (it sure does like a good horde...) I'm sure that's an arguable claim, though. I just don't think whether it's true or not makes the card more or less interesting. I'm pretty sure this combination of colors can do this, without really thinking too hard about it. That's good enough for me.

Whether it fits in Aer, though, is a more important question. It turns out that the token producing color in this block is probably black (due to the sacrifice theme). I like the card concept, but it's probably best saving it for another set, true.

The whole point of the cycle was to strive to make the activation color do something the casting colors both like to do also, or more accurately, something it can do that those colors can only do together.

I know that was your point in making them. I just don't agree that it's necessary. That said, I'm pretty sure I can't fly these cards by the 'panel' unless everyone likes them, including you, Link. So I'm going to give a few of these cards an extra go.

The activation here is so expensive, I wonder if it could perhaps be "for each creature you control"? That feels more red and white (Akroan Hoplite, Tears of Rage, Dogpile etc).
