Killing and countering Antimage

Recently, I'm having trouble killing Antimage (Magina). His low-cooldown blink which allow him to get in/out of team fight makes him an annoying hero, also this hard carry hero really get so strong as the game progresses on and provided he was able to farm well, he will simply dominate each of you.

Which hero should I pick to counter to easily kill this hero?

Some say that Lion is a good counter but I simply don't get why since Lion is a INT hero and as far as I know, Antimage is very effective against INT type heroes.
