It's a fat Elvish Impersonator
Its a fine commander, just a bit boring
The fact that you can destroy up to 2 cards means that if your opponent only has 1, you dont need to destroy one of your own
When you attack with a creature and it isnt blocked, you may pay the ninjutsu cost of a card in your hand and then put it onto the battlefield in place of the unblocked creature
If you have both cards down, that means in the average commander game you'll be able to pop a powerful spell on top of your library, draw it, then cast if for two mana up to four times a turn cycle
With support from ramp like Rakdos Signet or Dark Ritual, you can accelerate into Tibalt early and start to steal your opponents resources while you gain powerful card advantage
