A rioter replied on this topic before. It has to do with the thing creating the card is prismatic or not. And timelines applies a buff to your nexus. Considering we can't have a prismatic nexus timelines can't make prismatic stuff, that's the way I see it anyway. Honestly it should be changed. Good thing I saw that post before I picked a prismatic timelines myself
I'm happy to see my post was remembered. Thank you!
We are actively looking into how we can make the effect remember it's prismatic for this card (and any future ones).
