How to use BP for a normal run

I just won 25 BP in the subway ! Was wondering how to make the best use of it ?

I have some ideas :

• TM brick break : I use Lucario and it barely learn a fighting type move stronger than force palm until high level :/
• TM U-turn : Could be nice as I use Flygon and Braviary !
• Some cool items like life orb or focus sash

I play a totally normal run, no nuzlocke rules or anything, it's just for fun !
