Out of boredom, I started messing with the Shadow hunter, Banebow. I don't have 4 of every hunter card, but I had some good success with it versus the human mages, among others.

Banebow

x2 Gargoyle
x3 Brutalis
x1 Behemoth
x2 Fire Snakes
x4 Belledonnas
x1 Bad Wolf

x4 Death traps
x3 Into the Forest
x1 Careful Planning
x1 Surprise Attack
x3 Net trap (enemies can still defend though)
...

So I just played against a dark claw that, for the first time I've seen, wasn't a Teeth/superstrike build. I was so stunned that I had no idea what to do

I've been goofing off with various builds lately, and the only one I've had constant success with has been the Darkclaw build. This is what's been in my deck (no claims of originality):

Darkclaw

Allies
x4 Fire Snake
x2 Bestial

Spells
x4 Captured Prey
x4 Now Your Mine
x4 Regeneration
x4 Rabid Bite
x4 Here Be Monsters

Items
x3 Superstrike
x4 Teeth
x4 Lone Wolf ...

I'm sure these have already been mentioned but:

1. Having A Time Limit for Games (or give the option of a "Quick Game" with a time limit and an "Unlimited game" that doesn't.)
2. Giving the none human's an Aeon Style protector OR limiting 1 Aeon per deck
3. An Auction House of sorts for Rare/Epic cards. Let the players feast on their good fortune.

That's it for now. Interesting game
