Was playing the other day with a deck that had hanging chad, DNA, and hologram (plus lusty and I forget what the last one was.) Whenever I'd duplicate a card with DNA, it would show as triggering lusty +4 mult and then hologram x9.25 (or whatever it was at), and then hanging chad would make lusty show its +4 mult and then hologram x9.25 again. I watched it carefully -- hologram wasn't going up twice, it was just showing the trigger animation and its once-updated xMult total twice due to hanging chad.

Is dna per trigger?

DNA wasn't making 2 cards, and hologram wasn't crediting me for 2 cards, it was just showing the hologram gaining-xMult animation for both triggers. (Wow, DNA+hologram+hanging chad would go even harder if it was like "retrigger = duplicate the card another time" especially because I got red seal on one of my 5 
's later in that game and started duping that one.)

ngl it should do that, hanging chad is worst joker in the game unless you get a glass card and its really really early
but do be a weird visual bug

hanging chad is moderately useful if you have a few cards that have multiple buffs on them (like aura + material) or that trigger multiple jokers (fibo + onyx 8 
) or both, but yeah, I would generally rather have something else by mid-late game. But it is weird to see it "trigger" hologram to update its value twice.
Though as I think about it, it's possible that this is actually correct, and that what I thought was "because of hanging chad" was actually the first trigger from the card being added to the deck, and then the second was just regular scoring. So ... maybe this isn't a bug.
