Ok i see some your problumes
alot of your cards have 2 low of power
you should start buying card more tords 6 pwoer or higher 5 an lower will make it hard for you towin alot of matches dont get me wrong i do use a 5 power but only one an it is my dr.
you should try geting stronger cards.
Bad, bad bad..... First, i think you want a Mono-La Junta. (all cards are la junta)
So, get rid of Diego, Niki, Robin and Winifred.
Change them with:
Diego - Molly or Thormund (Molly for low budget)
Niki - Thormund or Wardog (Thormund for low budget)
Winifred - Dacote, Gertrud, Gatline or Bryan (Dacote is cheapest)
Robin - Tank, Masamu, Archibald, Bruce or Nahomi (I recommend Tank)
The others will work fine for your level.
By the time you reach level 20+, you might want to change other cards:
Myke - Tank, Masamu, Archibald, Bruce, Nahomi or Jane Ramba(don't pick the one you chose before)
Mitch - Keep the card, Tank, Masamu, Archibald, Bruce, Nahomi or Jane Ramba (still don't pick the cards you chose)
Leo - Keep the card, Tank, Masamu, Archibald, Bruce, Nahomi or Jane Ramba (still don't pick the cards you chose)
Winston - Keep the card, Dean, Wardog, Thormund, Molly (don't pick the cards that's already in your deck.
By that time, you should have:
now that's impressive!
P.S. I like to make myself look smart.
Your deck nearly made my eyes pop out. Get a Chiro for wall and damage, Nahomi for SOA killing and power, Tank for SOA, Archibald for pill + and Bruce for wall. Kick Diego, Niki, Winifred and Robin out. You would not like them to drag you in the mud.
What he's saying is get rid of diego, niki, robin and winifred. there your three weakest cards. he ssays that by the time you reach level 25, u would get this really awesome yet very, very expensive deck.
get masamu, nahomi, archibald and especially chiro for your deck. they're the next cheapest yet best cards you can get, especially chiro.
hope this helps.
