On a banner, you usually have a 4% probability of pulling a featured SSR (in a single that is, 33% to pull one in a multi) and around 10% probability of pulling an ssr (65% for a multi) the more there are featured cards, the less the drop rate for a particular one of them, this is why you struggle to get the main featured character in  a dual dokkanfests, since those usually have a lot of featured cards.

The best strategy IMO is to aim for the featured SSRs, rather than for the main one. never invest a lot of stones in  a banner where only one card interrest you. you can test your luck by doing a multi, the triying when the character is featured along other interresting ones
