If you would have gone looked at your alliance feed pane afterwards, you would have been able to click on each of the “recent” champs shown in ally feed.
If they are from your teammates, they will pop-up with the champ profile.
If it is a champ that YOU got, it will not pop-up. So you would have seen what champ you got right before the disconnect, once coming back into game and looking there.
Also, if it is a NEW champ for you, you would have been able to see it as “green highlighted” the first time you go into your champ roster afterwards.
