That's actually a really great idea, but it's rather difficult to formulate a decent team (20k combined attack), with only 30-50 cost, even if your cards are gold.
Even if you get 5 Gold Sniper Cecils, that just gets you 20k attack with 70 cost.
Nonetheless, what's with the amount of people spamming jugs nowadays?
I just fought a player who spammed 30 jugs just to fight me with a ~120 attack crew, when he could've easily defeated me using pixie crews, because my defense was near 0.
I originally thought he just desperately wanted that harpy for the event, but well... I could be wrong o_O;;
