Prism Array no long works unless my opponent has at least one creature out. If I get a landfall, no cards are drawn.
Seems like they decided to change it back to how it used to work.
Which lets be honest is much fairer, especially when you play against it!
I just want to note that the mini version of prism array since I don’t have prism array 
also now has this problem. Retreat to Coralhelm.
Just to reiterate, this is how the card originally worked. It’s still a powerful tool and at an appropriate level for a rare.
I don’t disagree, but because it’s not in the patch notes, it’s a bug, so we’re reporting it. Also I don’t know if Retreat to Coralhelm deserves to not work without an opponent’s creature on the field.
Sadly, we never get a full list of changes when big patches drop. The devs need to up their game with providing us information.
