Delta Nite, yeah, I knew what you meant.
And ALL of them have been edited since I started. Compare early Poison to current Poison (now with darker hues and more purple), early Bug to current Bug (significant color change), early Rock to current Rock (now with a rockier texture) and early Ground to current Ground (more noise, dusty look).
Still need to update the blanks with the new Ghost texture (the one found on the BW blanks).
The reason for editing WAS the fact that they were mostly simply recolors and I wanted to add variety.
