Basically the tittle, looking for a list (with pictures would be great) that contains any card that is NOT a pikachu card, does not have pikachu in the title of the card but still has pikachu somewhere in its artwork. 
Here is an example, note pikachu hiding in the top right
I love this kind of collection. It has all the right nuances of a unique and enthralling collection that shows a lot of variety. I know a lot of Promo cards feature Pikachu, so maybe look there. The first that came to mine were these:
2nd Anniversary Jumbo:
And the more recent Mimikyu Scream Card:
Good luck!
The website pokellector.com has a nice spread of all set cards including promo sets. Not sure about Japanese or any other language. I feel like thereās more random Japanese promos then there is sand on every beach in the world. So you can breeze through at least all the English stuff semi quickly on that website! I wish you the best of luck with this one pal, take it easy!
Every Raichu card printed as well, Pika in the evolution box
Thatās just evil haha
Thanks for the comment, ill see what I can find!
Thank you, I actually already have the mimikyu card and I donāt collect jumbo cards unfortunately. The massive size is simply too off putting for me.
Does this one count?
Thereās a good amount of stadium cards where Pika shows up
Lucky Stadium - Hokkaido Region version
Lucky Stadium - New York City Pokemon Center Version
Tropical Beach 2012 version
Pokemon Pal City - Kanto Region Version. A few of the region prints for this card feature that pika head dome seen in the background of the card bellow too.
Pokemon Park
Michina Temple movie Promo
Playerās Ceremony Promo
And finally the Champions Festival cards from 2014-2019
Then the 2 jumbos, one that @azulryu mentioned, pokemon plaza & then also pokemon valley.
Think thats all, probs missed one though 
Jumbo cards (if you know any other Jumbo card featuring a Pikachu Iāve missed, let me know; these I collect myself ):
Some other cards I have containing a Pikachu (completely unorganized, sorry about thatā¦):
(ignore the Bianca; itās a miscut with an XY Pikachu above it)
Some others that come to mind are most of the Trophy cards and the PokĆ©mon Illustrator (which is why I donāt collect cards featuring Pikachus except for the Jumbos, haha 
):

All from Scottās Instagram.
And there are most likely loads more I forgot about or donāt know about. Unlike Sevipers I donāt really collect cards featuring Pikachu, although I do buy them when theyāre affordable and I come across them.
If you need the set name/number of any of the cards Iāve showed, let me know.

@quuador, I was waiting for you to enter this thread! It had you name written all over it, nice post!
Really awesome replies from everyone thank you! Absolutely killer post @quuador , basically exactly what I was looking for.
I ended up searching through pokecollector.com after the suggestion form @mikejofthecoast .
Here are some cards I found that I havenāt seen anyone else show or mention yet. Not too many becasue I think we got most of them haha.
Great Comment thank you, I never would of noticed the pikachu in that lucky stadium
Oh, completely forgot about that Snorlax; will purchase one myself right away. And Iāve never noticed that Cubone had a Pikachu in the background. I might already have that card in my collection. The Copycat and other Full Art cards I already have (mostly in my FA Supporter collection).

Not seeing this one from Unified Minds in Quuadorās post:
Iām sure Iāve seen another one in the Hidden Fates set recently but I looked through my binder and couldnāt find it.
One very obvious one which appears to have been overlooked so far is Mr Fuji from the Fossil set:
Thereās also one on Arcade Game from Neo Genesis:
Another from Neo Genesis, this might count as a Pikachu?
The Southern Islands set contains 2 cards featuring Pikachuās lower half:
ā¦and Iām sure there are an awful lot more. I might come back later to find some more.
Of course, how could we forget about spaghetti arms Mr Fuji.
Thereās also the Tokyo Pokemon Center Promo
@quuador for jumbos thereās also the Pikachuās Summer Vacation Corocoro card
Edit: Ignore the jumbo thatās literally a Pikachu card
Iāve seen this card as well as the #41 WotC promo Lucky Stadium so many times on eBay, but every time I think theyāre too expensive (65-90 USD) to casually add to my collectionā¦
@pichufan Ah, why are those not in my Pikachu bindersā¦ I actually have every single one of those cards, haha 
The (Japanese) Southern Island cards I own are still sealed, though.
@dizzylochs Iāve excluded actual Pikachu cards (except for the Clefairy/Jigglypuff/Pikachu one, since the card is a Normal type). 
I could have included the Pikachu & Pichu Jumbo as well, or any of the other actual Jumbo Pikachus like these, these, these, this big one, these, etc. otherwise. I could add my entire 1200+ collection in that case, they do all feature Pikachu in the artwork.

Oh yea, obviously thats a Pikachu card and goes against the whole point of the thread. Im an idiot 
Nice catch @pichufan, espeically the neo genesis cards. I never looked that closely at them.
