In any case, if the cost is free, the cost area should just be left blank, so you should edit the card 1 way or another.
tried that, it still had the quanta symbol, and i didnt want to confuse anyone into thinking the cost was still 1, and i know there would be people confused about it
and i'm think it's hard to confuse with that thing
even this card have ability closely pillar/tower/pendulum you can use that card way to build your card, leave it blank
