Back-Alley Cagecrawler

Skulk
Whenever Back-Alley Cagecrawler deals combat damage to a player, that player reveals his or her hand. You choose a nonland card from it. For as long as you control Back-Alley Cagecrawler, that player can't cast the chosen card.
Vol Simalcra's darkest alleyways are now riddled
with the clanging of metal and the chattering of teeth.
