Yes. Generally, you'd want to focus on your "A team" first since you'll be using them most of the time. If the card ain't in your atk / def team, it will not contribute. BUT...

You will need them for Conquest events (10 strongest daemons of your deck), and also serve as alternatives during Tower events where you'd want to mix and match your daemons to suit the battles. ;)
