how to make a playmat for a trading card game similar to cardfight vanguard

im not sure how to make a playmat for a tcg, do i need to make a different object for the deck, field and drop zone area or is it one object or how else would be the easiest way to make 1.

You could place cubes with the mesh invisible and place the cards with those areas. The board itself is one big visible texture. Screenshot - 0cb2ec0bb374c2a8988079a58f89d812 - Gyazo
