What should I do with H!Sakura?

I pulled three of her and not sure what to do with her. The one I'm keeping is +ATK -RES, the second one is sub optimal and irrelevant and the last one is +DEF -SPD so its definitely not going to be used. With the extra two copies should I merge or fodder them? If I do fodder them what should I fodder them for and who should get their skills?
Thanks for any feedback!
