If team up with 4 friends maybe can deal more than 50m dmg.
I solo and met 2 guys (total 3 include me) willing to spend off their gold to buy all mines(total>150mines) and got 15m ending score.

use abundant farm as much gold as possible, then get all mines, except ursa full dps build.

Heroes i used:
Slardar burn, warlock fatal bond, troll ulti, skeleton life steal.

troll and skeleton can replace to other high dps heroes ~
one mine can deal approx 11k dmg and made the beast -1000% magic resist.
