Force mag question

[Agitokatana]

I have a force(and it's staying pure force, perhaps a dip in techer later down the track but anyway) and it's mag is monoceros lv. 104 with 55 T-ATK and 49 ability

I want to keep it as monoceros but I'm not sure where to go from here, any suggestions?

I've read guides etc. but I can't work out what to do with it or what other forces do so preferably someone that's been around the block a few times

EDIT: I was thinking of having it at 55 T-ATK 55 Ability and the rest in T-DEF maybe?
