LOL at least you understand to separately fuse the magas haha (they actually give the same exp [but it costs more silver] if you bulk fuse them when there's no BFSO; but during BFSO, yes, definitely fuse the magas separately)

I find that the following is pretty efficient for fusing feeders (maybe I should stick this into a page, hmm):

Fuse 3-5 other lv.1 1* feeders (type doesn't matter, although fewer feeders are needed if the same type is used) into the target card so that it becomes level 5 or 6

alternatively, fuse 1x 1* magatama of the same type into a target 2* or 3* feeder to make it level 5 or 6

I find that the exp I get from doing this is much more than fusing off lv.1 feeders, especially when it comes to 2* and 3* feeders ouo b the opposite is true if you intentionally level the feeders past level 6-7, though; level 5 is like a threshold since it doesn't require much XP to reach but requires significantly more XP (not a lot, of course, but still significantly more) to break past
