probably like instosis or something but once you get a fully upped deck i dont see muhc point to playing bronze
instosis is definitely not the best deck to farm bronze for a very good reason:
nobody farms bronze for money, only for special spins. when you go farm spins on bronze, you should be able to get at least 1 spin in 10 min of farming... with instosis, 10 min is equivalent to 3 matches at best, so you can imagine the amount of time it would take to get to the special spin using that deck
i actually use a fully upped mono shrieker rush deck with some quicksand and in 6 min i can get a special spin if everything goes right BUT there are far better choices when talking about bronze farmers
