From what I can recall, this mechanic usually appears on pack creatures - such as wolves. However, we've kinda seen it in with various pack rat type concepts. Idk, in black it would kinda seem like it would only buff power but maybe that's just me.

The mechanic is very much rats. That's where it came up first, right from the beginning.

So I'm amused to see it in black cats too :)

All things considered, I'm not sure why it's in Green... except for the fact that it's a good mechanical identity for Wolves. You would think it would be in White. "All of my phalanx are identical and are stronger fighting side by side" is spot on for White's philosophy.

Though I could also get behind White saying "We don't give bonuses just for showing up. However, we give bonuses when the team attacks or defends together."

Side note: Besides "Because wolves live in the forest" how come wolves aren't White 80% of the time?

Well, green can't very well be the creature colour if all the creatures head to white.

Mechanicaly... the green wolves are all over the place. etb draw a card, anti-coward, giant growth, make another wolf, make some food (ewww), draw more wolves, phase-punch, hex-proof, banding, infect...

Wow; creature-type: wolf is seemingly the dumping ground for "Not really a green mechanic, eh, make it a wolf" But I certainly wouldn't specifically say white.

(I do agree that the army-justification for "I have many of me, so I'm bigger" is a good one)
