Gunslinger, Spirit's Revenge

When Gunslinger enters, exile the top ten cards of your library. You may cast any number of Spirit or Equipment spells from among them this turn. Then create X Firearm Equipment artifact tokens with "Equip {1}" and "{x}: Deal X damage to target creature or planeswalker".

Whenever you cast an Equipment spell, distribute X bullet counters across creatures you control, where X is equal to that spell's mana cost.
