Food for thought on TFT (dunno if there is a specific place to put this)

So if this has already been touched on my bad, but:

What happened: I had a full team of predators and their complements when I drew an inferno off of wraiths. I put it on my Ez just for the ap, and a couple rounds after dragon drew steel Lux. During Rift herald, he dropped an inferno as well, but that still wasn't in my team comp other than Ez. I tried putting the inferno on my Lux with the idea that maybe, just maybe it would count twice since it is technically an origin? It didn't of course, but that brought me to the question of, why wouldn't it?

Again, not sure if this has already been touched on, but thank you for any feedback~
