Junkz are good for half deck use, I mostly see a Romana, Qubik, Tremorh and Flanagan( or Veenyle Cr ) half the time... I personally like using Montana and a Good Half I would use Waller, Desmond, Angelo and Edd Cr... I haven't really use Huracan but I can see a good Half deck using Derby Queen(cause I just love her), Wonder Lana, El Gascaro and El Matador(cause I love this dude)...Sakrohm is good too IMO, I would use cards like Nimestiec(cause a double attack manip. is good and a 2*) or Aleister, Murray, Mantiz or Petra and Jautya... this is just me though, I'm no expert... just love using these card so my opinion is biased..
Well think of decks that match with berzerks and create a consistent synergy. There are a couple of variants that can fit into berzerks synergy and mix based on your play style.
If you're an agressive player then Konrad variants may fit your style. Konrad+Lola/Roger+Elvis+Melanie and a atk manip clan or Pussycats.
Or if you are a control player then a 12* half deck with Elvis+Lola+Roger+Melanie and a SOA or SOB or Pussycats combo well
Copying a preset is only little what makes a good deck. Honestly finding decks that fit your playstyle and understanding all situations against every scenario is what makes a player top consistently or consistently have high elo scores
Thanks hollywood. that makes sense since often when i try out someone else's preset whose playstyle is different i rarely do well. but my own deck builds, like this one, i guess are easier to understand the important points and the specific importance of each card. for example, i usually shy away from Berzerk, La Junta, Pi Clang, and Jungo, being paired with pussy cats cause it seems too straight forward and obvious of a strategy but other people can do really well with pairings like this.
