So browsing through Jax's skins and found he has something in common with Jarvan IV

They both have a skin that uses Lu Bu's weapon.

Also, the Jax skin came out first. Wow.

Another skin to the to-buy list.

So now, there are actually 4 skins that are blatantly referencing the 3 kingdoms. The 3 WK skins and Temple Jax. Did anyone find any others?
