The preset is unplayable. You'll be wrecked by SOB.
Frozn's biggest weakness is that they have no character with more than 5 base damage. This implies that the best complement to a Frozn 1/2 should include at least 1-2 characters with at least 7+ damage. This is also problematic for Montana, another clan that also has fairly bad base damage. I mean, the Montana you chose have 1, 3, 4 and 5 base damage. 13 base damage for 12*s is way below curve: 12* should give you at least 16 base damage.
