Sasha is a Blue Moon CO who utilizes an above-average income to establish a unit advantage and limit her opponent's options.
Power: Market Crash -- All Enemy COs' Power Bars are drained by 10% for every 5000 funds she has. If Sasha has 50,000 Funds or more, all Enemy CO Power Bars are reduced to no charge. All of Sasha's units gain 10% increased offense and defense.
Super: War Bonds -- Sasha gains funds equal to 50% of the financial damage her units deal to enemy units, as long as the power is active. For example, if Sasha destroys a Full HP Tank, she gains 3500 funds. All of Sasha's units gain 10% increased offense and defense.
There a two very interesting things about Sasha to say: her day-to-day and her CO power
Her day-to-day allows her to get 10% more funds, which is a 10% advantage over normal 100/100 CO. She doesn't has any disadvantages with anything only an advantage.
Her CO power takes only two boxes to be filled, so she can easely launch her CO power. This sets her units at 110/110 and reduces the enemies power bar(s). If you make sure to have sufficient cash, you can make sure that your opponents can use their powers very little. This is especially nice on Team-games where your power can damage multiple opponents. Her CO power is also usefull in so-called zombie-games.
Disadvantages : She doesn't seem to have any disadvantages, however she has one. Her major disadvantage is that her (S)CO does not grant her much increasing firepower or damaging your opponents units. Her powers are usefull, but they can't help her to break through enemy lines.
