Yeah, I spoke to Fang a few days back and he doesn't seem to have any idea as to why it's down. I'll try and scout around but I can't promise anything.
If using photoshop, we just use "blending options" > "gradients" > "patterns". You'd need to define a holosheet pattern before hand though, theres alot around the net
I'm sure GIMP has an alternative to that too, if not using those 2 programs, it might be much harder to replicate.
Unfortunately, there is no dual type LEGEND blanks right now. As for the text, you can just use the Type Tool to enter the text in. I haven't figured out the font perfectly yet, though.
The font that I used for me and Xous' Reshiram/Zekrom LEGEND collab was Gill Sans Condensed Bold 8.5 @ 102% width. Don't think it's actually correct, but it looked correct on the actual card. Play around with it; type over a scan and try to match the font...that's the best advice I can give.
I had to make my own for that one sadly Char, but it was on my majorly small cards. I do intend to go back to Legend cards though with bigger resolutions at some point
Latios101's are the only ones out there atm dolphin, he's remaking them tho and shiningbill also has his own being made (both busy in RL though so might be a bit yet)
