I messed up hardcore -_- please help me rito... Mystery champ/skin issue

I recently changed my client to korean because the voices are so awesome (NA player). Well i woke up and get what i think was a mystery skin, but i searched through all my skins and didnt see which one was new (i have about 100, a lot from mystery gifts so i kind of forget the lower tier ones). Is there anyway i can find out for sure what i got because it doesnt show up in the gifting history now do i see a new skin (that im sure is new) that i got. Any help will be great thanks :D
