See Gold uncommon submissions.

Oh yes, very nice. There should be an anthem creature. I don't know what the cost should be -- pump effects can be really good.

I'm not sure what colour. UW is an obviously good choice, because flying + pump. But if we end up with too many WU creatures it could maybe be a different combination, possibly with slightly different stats (eg. WR +1/+0).

I like the flavour.

I just went by the cost of the Innistrad lords. We'll have more flying creatures (I think?) than there were tribal creatures for those lords, but this doesn't grant an extra keyword, so maybe it's safe? I don't know.

This is pretty comparable to Sprite Noble, and that was before the recent amping up of creature power, so it may well be fine. I don't know if it should be rare rather than uncommon though.

Like I said, it's based off of Drogskol Captain and friends, which is why I thought it was acceptable for uncommon. I could very well be wrong, though.

Mmm. Yes, that cycle were quite pushed themselves. I guess since Lorwyn we've had some tribal lords being uncommon (Imperious Perfect, Merrow Reejerey, Wizened Cenn) and some being rare (Scion of Oona, Timber Protector, Mad Auntie) - and that last link shows that some of those rarities shift up and down :)

So uncommon and rare are both viable for this card.

I get the impression that a little playtesting will go a long way. Round 1 Flying Men, Round 2 Flying Men, Round 3 Nightwatch Officer, Round 4 Concentrate sounds awesome. But I honestly have no idea if that's broken, or just plain solid. Guess we'll have to wait and find out.

Hm? This isn't Enlighten - +1/+1, this is just flat static +1/+1.
