You could win it less a more with any power given you spent enough rubies. A deck with 21-24k should be able to complete this location in 7-10 rounds. Oftentimes it is beneficial to join a guild to get at least a 50% color bonus for your deck. Try fighting once and see how much boss health you deplete. This wouldn't be a very accurate estimate due to artifacts bugs this time, but still pretty close. Then wait for 100% energy bar and use rubies and silver boxes to replenish energy.
