Grab your Belgian double barrel, and get ready to slay.
Feel free to re-arrange or tweak as seen fit, but the core of this build is ammo stash (Infinite double barrel), power reload (Increase mag size to allow for two shots) and mag coupler (aid in the reload timing). Technically this deck can be used with any character, though I would start as Mom to maximize the use of the belgian
Scattergun skills is to further enhance your reload speed, though feel free to replace it if its not needed. Likewise for money Grubbers. I usually have it in most decks to aid in economy for the team, but if you have a dedicated scavenger/economy teammate might be a good idea to replace that card. Though I place it to counter the small cost of Silver Bullets, while also allowing you to make more of a profit than with bounty hunter.
The purpose of heavy Hitter is to allow you to stunlock special infected and one tap common infected. And the reason for pyros placement is to emulate the use of the flame belcher to drop "armor shards". Later in the deck methhead is to simply further enhance the use of your fists.
