Every card collector, player, and just person who is fond of playing cards faces the same problem dirty cards
As a side note, I really love seeing all these details which are almost always hidden by the fact that the cards are cut down to size later on
The basic land types are Plains, Island, Swamp, Mountain, and Forest
As much as cards like Narci, Fable Singer and Satsuki, the Living Lore offer great utility, theres no beating Tom Bombadil
Cards from the actual Celebrations pack are legal in Standard, outside of the classic collection cards (which have no regulation mark), though some of those are allowed in Expanded (such as Tapu Lele GX)
Also because you can play cards you love even if theyd be terrible in a strict 1v1 format
