Hi Steve, a Sapper is one of the Champions and is used for League Fortress Defence.

I  have  seen  my  leaguemates  getting big  scores  like  1m  in  league  brawl  .

how  can  i  get  the  same  

i  think  only  bgs  is  not  sufficient

You need to play the Champion Tournaments to win Champion bonds. You might get a Sapper that way.

1MM points 

Awesome

SH Bgs, you can also combine both, normal and SH

Combinations of battlegrounds, Stoneheart trails and Champ runs will increase your scores for the Brawl. The tops score makers I have seen in the Brawl do very high level battlegrounds.

Thanks for the info titania

Thanks annabelle
