collecting also other cards would be cool,like the flying or surfing pikachu.
getting into the whole card collecting in the side of Pokemon is fun.especially when you have protectors of colors and glittery ones and binders to create a cool looking collection,shinies or holos are a cool adittion too to the whole collecting bizz.its a nice hobby aswell.
though,dont let yourself be eaten too much by the promos or editions or event cards.as this side is addicting,so there has to be a limit.
but overall,itd be a good hobby,as I myself used to collect alot of the first gen cards and second gen too,still holding on to my first promo card of mewtwo from the first movie.
im sure all 4 of them are desirable,but have a limit okay?
collecting in ebay and amazon and other places are also a really big hassle as buyers arent willing to buy a one card of an eevee for just 1,000,000$
but its funny to laugh at that too. so yeah,its all good.
