SoLeo Anderson (advices welcome)

I'm quite a beginner so I'm looking forward to your advice ! TY :)

Solo Deck for Leo Anderson :

• Fighting with 45. automatic (X2) or Machete (X2), with Prepared for the Worst (X1) if I have no weapon in hand at the beginning, and Vicious Blow (X1) for an additional damage if necessary.
• Investigating with guardian events (Evidence (X2), Scene of a Crime (X2) and Flashlight (X2) with an Unexpected Courage (X2) boost that I can also use for a treachery evade test.
• Bandolier (X2) to play 45. with machete and flashlight if needed.
• 2 allies to capitalize on Leo's ability : Beat Cop (X2) and Guard Dog(X2) , with Calling in favor(X2) if I want to draw Mitch, and Trusted (X2) to boost them.
• Healing with Emergency Aid (X2) that can also be used on allies, and Smoking Pipe (X2) to manage horrors.
• Lone Wolf (X1) and Emergency Cache (X1) for ressource gain

I'm affraid the deck is still too weak to investigate at times...how could I improve it ? I've got a feeling I could do with only 1 Smoking Pipe, and without Vicious Blow. What card can I use instead ? 2 Perception ?
