So, as you said, in the long run the card storage is the best thing to invest the rare coins in. You could also increase your team max cost (Although you'll probably not hit the cost cap ever again after the first few levels and after adding some friends. Unless you had 5 UR or something).

It might be surprising to you (or not) but story characters are absolutely terrible. Stay clear, unless you're a completionist and just want to add them to your album. There are no R characters that can turn into SR via evolution at the moment and I don't think there will ever be, but that doesn't mean to say R cards are useless! A selected few are very solid options for the beginner. Fire type Amelie, for example, has a speed debuff passive (it's one of the best kind of passive since it can be splashed in any element deck and still control the game. That's the reason UR Fenrir is widely used at high levels) and an awake skill that hits for major damage (that's SR level damage). Water type Jill has speed buffing passive for water, and the spotlight is her awake [Chain] skill. These kind of skill hit more than once and are very good as it will not target already downed opponents on the second attack, avoiding damage overflow and resulting more efficient.

And there are more useful R around, so you want to keep your eyes open and don't dismiss them just for they lower rarity. Also, keep in mind that the all-important speed statistic is so only for the 5 on 5 battles. When you fight raid bosses, they always act last so speed is totally useless. You want to focus on attack/defense reduction for your raid decks.
