Man you just don't get it. Bartolomeo's power is like children fighting
"You're stupid! "
" Nu-uh, you are! "
" Barrier Barrier, I made a barrier your insult just flew back to you"
"yeah well I made a Barrier, too! "
" Double barrier your barrier is negated and you can't make a barrier! "
Now how did you win these childish fights? That's how you beat Bartolomeo
