Looking for good mid lane champions, preferably easy mechanic

I like Karma and Diana, but the latter is a bit trickier in terms of getting the combo right. The former has a lot of versatility, you can shield yourself and allies, snare + self-heal and do really good damage with your ult that also slows.

I like playing and mid when I end up in mid lane. I'm not a mid lane main, so I play easy champs in that role. If I'm feeling frisky I'll play or .

Since you have Zed and Yasuo, you should try out Talon. Similar to them in terms of being an AD Assassin, but offers way more upfront and AOE burst than the other two.

Play Annie and have freelo :D

are all pretty simple with high damage and utility. Diana has the least of it but she still has a slow, and her fighter status makes her more of an off tank. Morgana is a funny matchup against many mid laners, especially Veigar. Her damage can surprise your enemy pretty well, and Karma's poke is insane.

Sounds like you still have to purchase champs?

Karma is a solid choice that can be a support as well. Pretty safe in the midlane and can be really good in midlane skirmishes

Zyra, Ziggs, Akali, Katarina, Kennen, and Brand.

^ All fairly easy to use mid/top lane champs. Brand and Zyra can be a bit tricky as you need to place things in certain orders to maximize their abilities. I personally prefer Akali + Kennen top rather than mid but they can work there too. Akali can actually give Yasuo a very very bad day. Also Anivia but her stun takes some getting used to (as well as how slow she moves).

, you just dump shiet, throw around shiet and press R.

Ziggs is good. He's all skill shots but they aren't too hard to land, good wave clear, has an escape. Can gank other lanes without even being there thanks to his ultimate

Karma, Lux, Morgana, Annie & Katarina.

I am a Zed and Yasuo main. I can play both pretty well, and I know how they work. If you want to play an easy mid laner Yasuo is no out of the question. He has like a billion passives and conditions to his abilities at the first glance, but when you really learn how he works, he's not that hard to play at a decent level. Zed is really good if you can play him right. When I first played him I was so bad I didn't go back to playing him at all. I returned to playing him after watching Redmercy on YouTube. Now he's one of the to champs I play.
