I would really like to see a new Karthus skin

I've mained since i started league (little back story i was really against playing league 8 months ago nearing my one year anniversary of playing but my friends got me to play and guess who was a freebie Karthus i was like oh he looks like what my playstyle would be so i played him and i did really well for my first time playing a MOBA and i just stuck with him (by the way League is the only moba i've ever played)he got me to lv 30 and here i am today playing almost every day doing really well and i think there's only one skin for him i dont have, of all the skins i have pentakill (mainly because i love rock) is my favorite to use becides grim reaper)With that little tidbit in mind it would be great if he could have another skin like maybe heart seeker (that'd be funny) or something that would work well in a group team comp (fnatic was kind of a letdown to me but that's here nor there)what i would really like to see though is a gurren lagann skin or some other anime related skin for him that would be great(Now then i think i spent far too long on this post so with that said im off)
