MagicalRecord import data for already existing NSManagedObject

I found a question like mine here, but I don't see any code in the answers.

So the workflow is next:

I create NSManagedObject using next code

[MagicalRecord saveInBackgroundWithBlock:^(NSManagedObjectContext *localContext) {

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"playerID == %@", responseData[@"player"][@"playerID"]];

Player *player = [Player MR_findFirstWithPredicate:predicate];

// on this line above player attributes are still the same at first time created. the player name is Alex if I po player.firstname in console.  

// on this line below i import new name for player - Greg.
// so I print player.firstname and the console shows me Greg instead of Alex.
// I think it has to update my value but it does't when I try to print our it in the success block.

[player MR_importValuesForKeysWithObject:responseData];

} completion:^{

// here I want to get my players assuming that there is only one Player just for testing.
NSArray *arr = [Player MR_findAll]; // print arr.count = 1 (just test if i work with one and the same entity)

for (Player *p in arr) {
NSLog(@"%@", p.firstname); // type first name and it is Alex, but has to be Greg, because I have print out it after import line and player first name was Greg. But now it's still Alex. What the problem is? 
}

}];

The next step I need to update this NSManagedObject using import feature. How can I do this?

Have a look at this blog post. It explains all the non-code related options to use the import functionality.
