The battle matches you and opponents by level. Say, you are level 60, you will most probably be matched to level 50~level 70. If you attack people 10 levels lower than yours, you don't get any BPs.

So, the following is what I think the low level top-ranked players are doing. They intentionally keep their levels low, so they are matched weak opponents. While they have lower stats than you, they do have much higher stats than players in their level range. And their deck cost is low, meaning they can attack more often without using power potions.

If you happen to notice, a level 2 player ranked top 100 in the last battle event. He can definitely win with low cost because he is always matched with the starting players or those who quit the game for a long time.
