Well, i find a way to do that. It's kinda gimmicky, but works.
I put a cardfunction as TURNOVER.
Then, i put the script in the card as "<s><a>y</a><l>Ativar</l><f>/cf;/c1;/ccg=1</f></s>"
That way, each time the card enters the field, it gains 1 counter. But if it is face-down, and we activate it, it flips face-up and gain 1 counter.
