Attack with Voss Treebender, exhausting an opponent's hero or ally in the process. Then attack the exhausted hero or ally with Bala Silentblade, dealing 4 damage (1 +3 ATK while attacking an exhausted hero or ally). And finally attack with your rogue hero wielding Barman Shanker to do another 4 damage (2 +2 against exhausted targets). A quick 10 points of damage. Attach a poison card like Deadly Poison to do even more damage, plus adding a re-occurring component to the damage.
