Anyone know the points to get more pizes?

I know I have a 4* card earlier in the game... i was wondering if there are any more cards later in game.

You mean during this event?

Point and battle rewards can be found on the event page, at the bottom where it says notice. Scroll down in the notice and at the bottom you will see the rewards tab.

for some reason, it doesnt do anything. I keep clicking on the battle rewards

Make sure to keep scrolling down, even after clicking rewards.

It's hard to click on the notice texts on ios devices like ipad touch, screen's not responsive for some weird reason on Notice section. Have a much easier time on my galaxy s3 for that...

To answer your questions:

it's every 3000bt after 6000bt for 3TE each time

and 30 win after your inital 30 wins for 3 pots each
