Not this guy. With him, if you give up like 30 cs and 2 tower plates, you can out-sustain him and use Phase Rush to run away and find a kill angle.
This one is the worst. Sustain is almost even, and because of his ult you can't just Phase Rush and run away. If you call for a gank, he just ults your jungler and it's a counter-gank.
Teemo, Vayne, Varus, Caitlyn. Gross.

At level 1, Morde's gonna put a point in Q and sit in the second bush. Stay as far back in that bush as you can, and once he misses his Q, go in and trade hard. Then you have to go for the kill at level 2. He's saving W for sustain? Insta-flash in, auto-E, and as long as you dodge his E, the kill is yours. First item I'd go Bami's Cinder.
