One way to creating fake cards is to start with a real magic card, and then make it look like a more expensive version of the card
This means older sets are moved out of the Standard format, easily the most played and most widely supported format
Its quite easy to make modified creatures with mechanics like job select and living weapon that create tokens to attach equipment to, not to mention whites plethora of counter production
Its made only by commons and upgraded/curated, by a community
Setting aside color requirements, Siege Rhino is a 4/5 instead of a 2/4, costs a mana less, and even has trample
Also, most non- EX Pokmon rely on Special Energy cards, so Aegislash- EX ( XYPhantom Forces, 65/119) perfectly pairs with Klinklang to pick apart many decks
