Everything else you need a 3 win streak for all 7 matches, then the 7th match on your 3rd runthrough you will fight the brain.

What he means (Sorry lol ) Is for everything else, you need a 21-win streak for the first run-around with the Frontier Brain (Or Tower Tycoon, in Palmer's case). Your 21st Battle will be with the Brain, and for the second battle, It's a streak of 49 to battle the Brain again, for a coloured medal.
The only exception to this is the Battle Hall, in which you need a 50 battle streak the first time, and a 170 battle streak the next, and you have to get to rank 10 on every type.

Thank you

Lol no problem, as long as he understands. It doesnt matter to me, but yeah dont expect an easy fight, listen to the music too.

Ok
