Sub-classifications

[Illyasviel]

Consider me a proponent of grrl power, or a pervert as you will, but I want to make an all-girl deck. And since the cards actually have a 'Female' sub-type, I'm wondering if that will ever come into play down the road, or if I will just continue to use a multi-region Card File with a pretty doubtful chance of victory? Doesn't matter, I'll have fun either way. (And no, I did not mean that to sound as bad as it did, haha.)
