@NinjaFrog77 Hey Kevin, just realized I read your question wrong. If no one else joins a battle then you do not have to use a champion to get your own card back. If other players have put cards into the pot, but surrender you also do not have to use a champion.
@NinjaFrog77 Hey Kevin, I know this is super slow, but yes. If there is only one player left in the battle they still have to use their champion and can't change it.
We are excited to announce that Clash of the Cards is not only back in stock on Amazon, but has an awesome new box and higher quality cards. It's only $12.99 until 12/1. https://t.co/OOEdIJgeLT
