I built a zoo deck yesterday and think it works fine. So today i opened some packs and i was supriced to get the 4 giants used in a "giant" deck. Also got about 1.4k dust. I don't know if i should craft upgrades for zoo deck or try to make a giant deck.
What do you think? Also, which one is the best legendary as lock? I haven't got any legendary at all atm.
