Anyone who is actively playing Teamfight Tactics knows that in Carousel you should first look at items, not champions (unless you can pump a rare hero). That's why I've compiled a list of the best must-haves in Carousel Mode.
Best items in the first rounds
Replacement options
In subsequent rounds, rarer champions and sometimes improved items will be offered. If you are not offered anything better, your choice is still based on the five items listed above.
