As a commander, he is a build around one and will not create insane board states that explode or devastate your opponent's side of the battlefield. His gain counters ability wants you to play Voltron, but there are better Voltron commanders than Drizzt. I would much rather have Sigarda, Host of Herons who has built in evasion and is difficult to remove than Drizzt as a Voltron commander. However, Drizzt is a commander you can work around to create a counters deck and add some mischievousness to your board. He is not the cause of the mischievousness but provides the framework for an alternative brew.
