Hi! This is the relevant link

My middle ground would be to count any shiny cards in the collection. I'd say a shiny cards in the deck counts 1x and a shiny card in your collection, from the God's domain counts 0.2x, so you'd need 5 not in deck to count as 1 in the deck. This still gives value to shiny cards while allowing people more freedom and not punishing people for optimizing shine instead of competitiveness.
I didn't buy Diamond cards on purpose for DPE, so I don't feel obligated to play the same deck all the time. So I change decks frequently and I try to find what is working for me at different times. Being able to rent helps a lot, although now one needs to be careful and do the math on the renting costs. Playing Formats also helps a lot with diversity and I see people playing with shiny cards there as well.
Also could you please put a source link of the gifs in the posts as well? Unless you made them yourself :P
The gifs are all free to use via tenor and linked in the gif themselves merely right click for the link location. There is a reason it is enabled within the peakd keyboard friend. They are actually just hyperlinks.
Seriously though, joking aside all gifs are linked in and of themselves and free to use and filtered into the peakd keyboard application for this exact purpose. Appreciate the zeal, but that's all kosher. There is an article on it published a while back when the "GIF" part of the keyboard came out.
The gif itself appears like this and is actually linked when posted via the keyboard to not require double sourcing. It's by design.
Just clearing that up, they are linked by default to the image source itself. Tenor is a public image repository with various image sources that allow free use. Appreciate the shine meta link, but I'm pretty sure if I use the peakd keyboard gifs they are kosher. It was the whole reason I was using them lol, if you want me to format it to double link w/text I can do that it's no biggy or if sources are just getting cracked down upon harder I added them.
