What to Buy?

So I'm trying to decide on a 1350 skin to buy, but I own a lot of them.

It's hard to decide between:

1. Mecha Malphite
2. Warring Kingdoms Jarvan IV
3. Knockout Lee Sin
4. Risen Fiddlesticks (already own Surprise Party though)
5. Dragonslayer Pantheon
6. Steel Legion Garen
7. Masked Shaco (I know it's 975 but it's still a cool skin)

Any skin I didn't mention I either have or just don't care much for, so please don't suggest anything I don't have listed. I know the PROJECT skins are coming out but I can just buy them when they do with the money I get later.
