Narox, Emissary of Diversion

Flying, Haste

Whenever you cast a spell from anywhere then your hand, you create a 2/2 blue and black nightmare creature token.

If you dealt combat damage with tokens you control, you may sacrifice any number of them. If you do, they deal X damage to target opponent. Then you may reveal the top X cards from your library and put up to two creatures onto the battlefield, and shuffle the rest on the bottom of your library in a random order.
