You said Shadow Hand, which makes me think stealth... Whispergnome gives +2 Con (but -2 Str) and great stealth. Human is as always a decent choice. You might also consider Dragonborn Water Orc... +4 Str, +4 Con, -2 everything else and you get either really nice senses, a breath weapon, or wings. Also, you can swim quite nicely. Strongheart Halfling takes a strength penalty but gives you a feat and you're small. Buouman (sp?) gives +2 Wis and I think -2 Cha, so that might be worth going for too.
