All In (Prime Weapon Joker): When equipped, the other weapon slot is locked in the saloon loadout menu, preventing you from equipping another weapon with this perk (or don't prevent them and let players remove both weapons for the funny). Deploying with this equipped will remove the other weapon. In exchange, you can pick up any ammo crate to restore this weapon. This allows you to utilize more of the ammo you come across on this specific weapon.
Alternatively
All In (Legendary Weapon Joker): Same effects as before, but it also grants 2x ammo bag (including boomerang, allowing you to have two boomerangs).
