Counterattack option

So something I was thinking might be an interesting concept is that of a counter-attack in the arena. The way it could work is if you get the message “you are currently engaged in battle” you get the option to use one of your arena battles to counter attack the team that’s attacking you. You’d be limited to only using whatever team was in the arena for you when you were attacked, but if you win you don’t drop in rank if your opponent wins their match (or, if they finished first, you lock them in battle until you’re done and then you switch back when you win). That would give players a chance to fight back against getting sniped at payout time, and be a fun way to get back at “rivals”.
