Here are the challenges to complete, and the rewards in order to gain the Mileena card..
If you have been playing the game regularly, the Challenge will be a breeze.
In fact, it's way too easy.. I believe I won all the fights without even needing to swap between the 3 characters I chose.
One of the things that I miss from the Injustice Mobile game was the chance to continue beating the challenges at a progressively higher difficulty setting to keep winning more Challenge Cards to fuse them together.
That would have definitely gave me more incentive to level up my other cards to be ready for these challenges. At the moment, I don't see any point in level-ing up my bronze cards and most of the Silver cards.
With a tough bronze card Challenge to earn more Mileena cards would have made me play the game more to boost my bronze cards.
So, yea.. took me less than a day at work to complete the Mileena Challenge and here it is!
Her skills look like this will be a strong character to have level-ed up. But my sights are set on the NetherRealm Pack at the moment..
Her card profile..
And since there's no way to fuse it, via winning more challenges...
350 Souls to fuse it once.. Highest out there I believe, so she better be worth the trouble..
And her Support Cards..
Definitely looks a strong character and there's definitely not a challenge with earning this card so you might as well...
There's still plenty of time.. 19 days in fact so good luck! Wait.. you don't even need luck..
