Show previously answered duels and have ability to change choices if & when desired.
I think there should be a personal statistics page created for each individual’s contributions to the Face-Off. The statistics page can show all previously picked Pokémon within their respected duels.
This should also enable the ability to change each decision previously made.
This is especially important for people who may pick Pokémon without really knowing what they are picking and/or may wish they had chosen differently at a later date. Without this feature, if someone later changes their mind about a previous duel they will not be able to change their choice.
Thaaaat could get long. But it would be useful for those accidental times when you fail with touchpad. Perhaps just a "back" button?
