Overview
Walking the floors of the Honeypot, Mr. Tannen invites himself to a chat with the patrons. Suddenly, their winning streaks turn sour, and piles of chips disappear bet by bet. Mr. Tannen is very good at debuffing the enemy crew. He can reduce the enemy hand size by removing Arcane Reservoir, stopping models from drawing cards, or using Equalize Fate to reduce the opponent's hand size to the same size as his controller.

Mobility
Mr. Tannen has 4 Wk, and no charge. Shambling helps him get through severe terrain. His Immune to Influence prevents him being lured, obeyed or pushed by his companion Mr. Graves however.

Offense
Melee
Mr. Tannen's melee option is his Pocket Knife. It has a mid Cb, and no triggers.
Ranged
Mr. Tannen has no ranged attacks.

Resilience
Mr. Tannen is Immune to Influence and Pitiful, making it harder to pick him as a target.
Due to Cooler, enemy models trying to cheat fate within 5" of him must discard a control card before cheating fate. This can make your opponent burn resources to ensure their actions occur near Mr. Tannen.

Tips and Tricks
