are gallery cards just lore?

[Jurro]

if so i mean that's kinda neat but i could just google that stuff why would i want it as a reward or to get it on the battle pass?

They are just filler, the reward for them are the rewards you got unlocking them through the missions, it's a free game and they cant give away too much of the blue and gold currency that said if you own the battle pass you should unlock the last card only when it's the last thing you are missing

After few seasons it will be a reminder... just like this Jeff postcard that you are currently making. I played LoL and dont remember most of events that happened in the past so its a fun feature for me... and it have some lore slapped on it as well.

Thats why page is a final piece to optain. Its a reminder that you actually completed it.

Collectable items on the other hand have no reason to exist /lol
