I wanted a simple ability that would interact with allies and planeswalkers. Et viola.

Intriguing. Feels not-quite-common, but I guess it's just Clockspinning, so should be okay. I love the idea, but I do feel Ally cards are easier to read if "Ally" is capitalised (as it is on printed Allies like Kazandu Blademaster).

Yeah. I don't think it's too complicated in absolute terms (several proliferate cards were common), but (a) it only works if there's good reason to have non-+1/+1 counters associated with allies and (b) there's enough of a theme in the set this doesn't stand alone. So, maybe.

(And thank you -- yeah, I totally agree with the formatting, it was just typos.)

I really liked the Allied themed Planeswalker and Allies, and conceptually, they're all very good. Had I worked in development, though, I'd probably move to have this card struck. It's a great idea, and would probably still be a great idea if it was splashier and rare, but by itself, and with other Acolytes, it's just a grizzly bear. I know what the card is trying to do, but unless 50% of the creatures in block come with counters (unlikely), he's going to dissapoint a lot of players on round 2 a lot of times. When he's a good card, he's great... I just don't know if that's worth when he's a bad card.

Well, on the one hand, I agree, this is too specific to make a good card in a real set; I was stretching to make three cards that I thought had interesting links, and if you lose the connection to the planeswalker this can become "put a +1/+1 counter on target creature" or just be killed. (The same applies to the Archmage, even more so). But on the other hand, half the creatures probably won't have counters but half the allies probably will, which is what I was thinking when I made this.
