Prism array bug

I noticed that prism array doesn’t’act if the opponent doesn’t’have a creature on the table while the card doesn’t’ state that as a requirement (just that when any player landfalls opponents create is disable and you draw 3 cards)

I assume that that is a bug? icon_e_surprised.gif

I posted this same type of bug with the “Retreat to XYZ” cards. If the condition of a creature isn’t fulfilled, nothing triggers. The wording needs to be changed or the bug needs to be fixed!
