Mostly happens to have more than 1 kind of token on the field during combos
would be easier to pull out different tokens with different pictures (of the existing ones)
(ps. there are so many missing in the token picture choice)
allowing the choice of max. 3 or 4 pictures that can be choosen (as usual) in the deck constructor while building a deck
putting counters on them (to make the difference between tokens) :
first makes the thing confusing for many (not allowing a play on a reasonable pace)
second it's not even legal to put random counters on monsters,
third if you or the opponent also play counters to put on the field , would make it less clear than it would already be.
