I thought it might while in game the match can be recorded ( just for entertainment ) so you don't always have to searching for people to watch cause they have had it recorded and you can look up a match you wanna see from low lvl to high lvl. Also it doesn't have to play like a video but where you can just go into port into an arena watching bots of their wizards do everything that happened in the arena and spectate it. Just something i thought of but idk if someone already mentioned this but yea. Also to add there can be a button option where you can go back turns and forward or pause the match.
If you didn't understand most of what i was trying to say, i'm sorry cause i'm bad at explaining things out properly
