I Played Oh-So-Evil Evelynn and...

She's really fun!

She's not mechanically hard to play at all. It's just a bunch of spamming on the target you want to kill. However, it's a matter of when and where do you attack. You skirt around the edges of the enemy's vision, waiting for them to extend a little too far, and BAM! They've been ripped apart... ;) And she's got one of the best dances in the game, if you know what I'm saying... It even feels like you're tearing them apart with all the button mashing you do.

I'm not really good at telling if a champion is viable or not. I play a whole bunch of off-meta picks. However, she's really satisfying to play. When she gets updated, I hope they keep the waiting game, and the feeling of ripping someone apart with your claws. >:^)
