Narain giving two cards instantly rather than creating two holographs for a decision. Playing a Renathal HL deck in standard. Even made sure hand had room for additional card. Didnt matter. I did have two Narain’s from creation protocol if that makes a difference.
Edit: Also played a Disguised K’thir to summon a warrior Titan if that makes a difference. K’thir was not from Narain.
Narain instantly gives you 2 cards in hand that are at all time (in your hand) copies of the top card of your deck.
Is that not what you experienced ?
They werent copies. Narain gave both cards as full cards with no holograms present. Just straight up cards. I didnt even play a single Narain hologram. I had 3-4 lightbombs in hand without choosing lightbomb at all. I selected Narain for creation protocol, played Narain, ended up with 3-4 light bombs in hand after two turns. I did draw the original Narain if that makes a difference. The interaction is bugged. I gave the pertinent information in original post. No way you can end up with several light bombs in hand on turn 6. I wasnt even running dryscale deputy. After lightbombs were givin no additional Narain holograms present for selection. Straight bug. 
Edit: I think what’s happening this patch is the Narain holograms that once were are showing up as straight cards. Only visually bugged compared to what we had before. I kind of liked the holograms tbh. Reminds you what the cards actually are. Can get confusing when playing duplicate cards such as Dryscale Deputy and Creation Protocol.
