Hmm. When making this card, I sought to make an enchantment that was generally better than Strength of Unity. Obviously, those counters have a use outside of the aura, but I didn't get away with strictly better. I could up the cc to 5, but, again, not better. I don't know why that bugs me. This card seems plenty powerful for a common.

Ha. This seems worse than SoU to me, because that would increase its bonus if you draw your missing land type the turn after you cast the Aura. See also Opaline Bracers.

I know, but it's killer in the set. Look at what this would do to Ionized Nantuko alone if you payed four colored mana. The card would be a 8/9 First Striking, Trampling monster attacking on round 5. It's enough to make me think that this card is destined for uncommon.

It's just confounding because I've always liked SoU, but thought that it was just a tad below the curve to be taken seriously. In set this is a monster, but outside set, it's much worse. Just odd.

I don't know. Invasion had Razorfoot Griffin, which could have attacked as a 6/6 flying first striker on turn 5 with SoU (assuming 4 colours; 7/7 if a turn 3 Harrow got you to full Domain). On the occasions that people manage it, they'll feel awesome, but I don't think it should be that frequent.

I'd say to try this as it is; if it's a problem then by all means bump it to Uncommon.

Good point and fair enough.
