SImple enough question.
Which card art from Pokemon tcg would you like to see made into a full art card? Any rarity, any artwork, any era.
For me, I have a love for the original base set squirtle. Love the dynamic pose and think it would be an awesome full art card with the texture on the water.
Nidoking please!!!
Just as Cynthia received a full art with shiny Lucario and shiny Garchomp in Ultra Shiny GX/Hidden Fates, Lance deserves similar recognition
Lance full art with Dragonite and red Gyarados
Base set hitmonchan with shadowless coloration
Scyther. But Scizor always steals the full arts… jerk.
KLINGKLANG man, there is some serious engineering going on in those gears we need a full art to fully grasp the technological expertise present there so we can apply it to society.
Typhlosion Feraligatr and Meganium!!!
Never enough love for gen 2 starters 
Victreebel, Politoed, and Kabutops, please.
I want base set magikarp art extended so i can see who is at the other end of the line.
Also expedition dragonite. I feel like there is a story there I’m missing out on. Like he is landing at a picnic or something.
This will be no surprise, but it still triggers me that we have no full art Politoed cards (or any Politoed chase cards for quite some time, in general).
Dratini
Full art typhlosion or any gen2 starters would be so awesome to see!
More full art pokemon with their trainers like from cosmic eclipse.
Geodude + Brock
Starmie + Misty
Gengar + Agatha
Magmar + Blaine
So many possibilities
M Charizard X
Moltres
Regice
Arcanine
Lt. Surge
Typhlosion
Meganium
Feraligatr
Kabutops
I want pokemon that later got another evolution that takes all the rare card slots instead of its pre evolution.
Onix, magmar, electabuzz, togekiss, porygon 2 etc.
For that matter, i would absolutely love some sort of mini set focusing solely on elite four (different generations). Imagine having that Lance you mention, Lorelei with her Lapras, Agatha with Gengar, etc.
Would pay some serious money for that to happen.
^^^ I NEED ALL OF THAT.
Pre ordering 4 booster boxes right now just in case it comes to life.
Typhlosion
Aegislash & Klefki Tag Team Full Art
Charizard & Blastoise Tag Team Full Art
And some weird body cards like Skyridge Charizard or FRLG Charizard.
Also Haunter. One of the best non-fully-evolved Pokémon.
