Tomas here is rather versatile. Cheap, no upkeep influence? Check. Huckster 1? Check. Ability that can save the day? Check.

Start Tomas in a high value Hex deck (J,Q,K), and opposing weapons will be a concern of the past. Load up on zero cost spells and enjoy the economic advantage. Or use him to send a key value in your draw structure back into your deck. Use him to make use of certain "meta-game" spells that are not showing their usefulness right now.

Drop the value plan down to 10's and you can Shadow Walk in, and blast something like a Legendary Holster or Adler's Needle before it ruins your day.
