These two took me by surprise. I originally wanted to add Dragon Slayer Jarvan to this, but there was literally NO WAY of making it work. Instead, I made it so Vayne and Shyvana were against each other. The way Shyvana's art was made brought about difficult angling. Even though they're not head on with each other, I will not lie; this is my favorite merge I have done.
