When revealing a champion at the start of game 1, if you have multiple different champion units in your deck, can you select which one to use during game 1, or must you pre-select a specific champion during deck registration?

Ruling: You must register a chosen champion into your deck during deck registration and use that specific champion for game 1. You can change your champion choice before game 2.

Sequence:

• Register a specific champion with your deck
• Use that registered champion for game 1
• You may change to a different champion before game 2
