Plz bring back Poro rider Sejuani

I have never bought RP from league before, but when i saw this skin i knew that i had to get it, unfortunately in my country the cost of RP is double the actual price because of our currency. when i finally got the RP i needed, to my disappointment the skin was no longer available. I really want to know if it will ever be available again? Is there any other way i can purchase this skin or are my efforts here useless. Please respond
