I dont think so maybe if you have good low stars card and you use the best leaders ells no i dont think it is
Try a Hudo deck, filled with high powered 2 cards and 3 cards like Sentinels/Junks and Defensive side like Uppers or Pussycats combined with Hugo, IMO the best leader.
Well it is good but also leaves your deck open for an attack i tottaly anhilated decks with the hugo combo...just cause there deck wasnt complete so in my opinion i would say no
Don't use asigaru, vansaar, or ambre
vansaar and ambre are better for evo
For 5 stars I prefer a high powered hardhitter like Lamar or Tanaereva. Although maybe Morphun can be placed as the only nonclan card in a single clanbased deck.
