In Commander, where mana is often plentiful, it's fairly easy to get Tuskcaller easily up to Level 2. Therefore, with the untap shenanigans that exist in Commander, this card can be quite abuse-able. This is the primary reason that the Tuskcaller was selected to be a reprint in the Evasive Manuevers deck led by the widely hated Derevi, Empyrial Tactician. But interestingly enough, Derevi is not the Commander that plays her the most often. It's actually the token-happy Trostani, Selesnya's Voice that utilizes her talents the best.
She's no money card, but she's solid in any token-creating deck or any deck that abuses tap abilities. Her mana-hungry Level Up ability turns a great many players off, but once her token creation ability is online, she's better than you might at first realize. Kazandu Tuskcaller is a solid addition to any Commander player's arsenal.
