Cards that are good for campaign are the ones with skills that deal damage to all enemies. The best ones are Artemis, Yuki Onna, Sekhmet and Pyromaniac because of their 30% chance but they are very hard to get (Artemis is gone, Sekhmet takes a long time to get, Yuki Onna is an Evolution Accident and Pyromaniac is Step-Up Summon exclusive). The easiest SR you can get now with that kind of skill would be Destroyer, but she is 20% chance.

Campaign teams should always have 5 cards: The Main Attacker should always have full soldiers, on Max Level and her skill should be maxed too. The other 4 cards are there just to give you more time and they only need 1 soldier (you can use turn skip cards for even more turns or Critical DMG cards if you are going to battle a boss for a chance to do more damage). You can put soldiers on your other 4 cards but that is a waste of resources in my opinion.
