I believe the confirmed new number of Pokemon for Isshu is 156, bringing the total to 649, knowing that, how many of you can make 649 good, unique designs? I know I can't.
(Also, take off your Nostalgia Glasses, that may help...)
1/20 of the drawings I make are concidered "awesome", so imagine that with pokemon. Yeah, definetly is tricky to get 649 creatures made. Evolutions, movesets, descriptions, all that stuff. VERY hard.
