Illegal interaction with Ragavan and Archive Trap
In a Timeless match, I hit my opponent with Ragavan Nimble Pilferer, and exiled an Archive Trap with its trigger from their library. I fetched afterwards to cast a creature, but then I realized the Archive trap I exiled displayed a 0 mana cost, as if my opponent searched library. I attempted to cast the spell targeting my opponent and it resolved.
I'm not a judge, but I explained the interaction to a group of them, and their conclusion up to this time is that it is an illegal play given by rules 601.2a and 601.2f, since the spell cares who the opponent is after it's controller (not owner) attempts to cast it, and not while in exile, owned and controlled by my opponent
I forgot to screenshot the exact match where this happened, but I'm attaching my log of the day if it helps in anyway to either determine if it is a legal play or to fix the bug

I also ran into this interaction today, except I was the player being hit by a Ragavan. I looked it up and it seems to have also been a bug in the MTGO client.
