Ill break things down by color since there are cards from everywhere making it in
I have had situations where I knew the top card of my library but needed that card sufficiently badly to aim a blind Predict at my opponent to likely draw just that one card rather than mill that card and take two unknowns
While I cant find anything confirming why this is, its likely because its on the Reserved List, so Wizards is hesitant to errata something they cant reprint
Combined with the fact that so many people have a soft spot for the starter Pokmon and their evolutions, it's understandable how this card is now valued at such an astounding price
