Possibly should cost more?

­Porcelain legionnaire was really really good and cost for 3/1 first strike. This is probably comparable: 3/3 fs is not that much better than 3/1 fs, and being able to come down on turn 2 was a big upside to the legionaire. IIRC the GDS2 comments said white rarely gets a 3/1 at all. So this is probably at the very top end of printable, but you probably don't want white to be quite that aggressive.

2/3 seems a lot weaker though (it should have bushido or some other add.) Any suggestions?

Hmm :) Recently I seemed to be playing against 1-damage burn spells and 5/1s so I would have loved a 1/3 first strike :)

I think there's a range that's acceptible. I assume you want 3 power by default?

2W 3/1 is fine (a bit weaker than porcelain, which is fine, you might be able to do 3/2) 2W 1/3 or 2/3 is probably weaker but still very playable and plays the defensive flavour 2W 3/3 is fine if you're happy for it to be very good. 3W or 4W 3/3 is plausible as a replacement for the big-white-buy slot.

I would just pick one for now and then later on see if the rest of the set suggests you want an aggressive creature here, or a bigger one, or something else.

Yeah, gotta agree, against most modern limited match-ups, this isn't fair. Just compare this card to Nessian Courser, which I would call a solid draft pick. Or, if you want the other extreme, you could compare this to Battle Hurda or Siege Mastodon, which aren't great cards, but they help fill out the curve and are certainly playable. ­

2/3 First Strike seems more appropriate, and can tackle a fair number of commons. In theory, this sort of leap above the curve does and can happen, but it's normally reserved for uncommon.

Fair enough. They're supposed to be dwarves too, so let's make it smaller.

And having power 2 lets it work with Dwarven Warriors too, which is a nice upside.
