­Call of the Conclave/Watchwolf/Kalonian Tusker is normally uncommon. Though I suppose Swordwise Centaur and Garruk's Companion were common. Seems a reasonable card, if not a particularly interesting one.

Odd that Wotc seems to put that one extra toughness as a reason to make things uncommon.

Somewhere there's a piece where the designers talk about what P/T creatures tend to get in different colours at different rarities. I suspect total5 vs total6 is the boundary for green common.

Hmm, I'm working on trying to get a handle on designing commons so I'd like to keep this common if possible. Would I need to cost this at or make the token a 2/2 and cost it at ?

So there are a few things to bear in mind.

• Normally, being a token is a downside rather than a benefit. In other words, Watchwolf is normally better than Call of the Conclave. It's less vulnerable to bounce, easier to recur (Raise Dead is 1 mana and common, Call to Mind is 3 and uncommon), and so on. (Return to Ravnica was an exception where Call of the Conclave was actually better than Watchwolf would have been because of the populate mechanic.)
• The standard vanilla common for is 2/2 (Runeclaw Bear), but you get significant upside on that (there are many things with those stats but strong abilities as well). The standard for is 2/3 (Elvish Warrior) or, pushing to the stronger end, 3/2 (Swordwise Centaur). The standard for is 3/3 (Nessian Courser).
• The standard price for a 3/3 used to be - Trained Armodon, Gnarled Mass. However during that time period they also printed Call of the Herd, showing how much weaker tokens are than creature cards.
• Wizards generally prefer to make tokens have the same power as toughness. There are exceptions, but especially on commons, a 2/2 or 3/3 token is better than a 2/3 or 3/2, partly because many people use dice, glass beads or other things to represent tokens.
• Wizards also generally prefer to keep most commons having a single coloured mana in their cost. Most sets will have a few double-coloured-mana commons, but in most sets, the large majority of commons should be single-coloured-mana because that makes two-colour decks in Limited smoother.

Putting all of that together: since Nessian Courser is fine for common, you could definitely make this a sorcery making a 3/3 without causing any surprise at all. That would be a medium-to-low strength card; the token could have trample or reach and still be fine. You could also make this a sorcery making a 2/2, and again you could give it an ability to make up for being worse than Runeclaw Bear.

Thank you for all of that wonderful information. I think I like the idea of a 3/3 reach so I'll be going with that.

Er, that suggestion was assuming you also increased the cost to (2)(G) :)

Sorry Had to go change a diaper so i had to save quickly.
