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
