Kylox, Visionary Inventor

Description

Kylox, Visionary Inventor (MKM-365) is a legendary Lizard Artificer creature from the Murders at Karlov Manor set. It has menace, ward {2}, and haste, and when it attacks you may sacrifice any number of other creatures to exile the top X cards of your library where X is their total power, then cast any number of instant and/or sorcery spells from among those exiled cards without paying their mana costs. The ability resolves immediately as the attack triggers, using the sacrificed creatures' last-known power and allowing you to cast spells regardless of timing restrictions, though alternative costs and unpaid X values are handled per the rulings.
