bloodhunter should be one option if he's relying on blink to get himself out of ganks
silence + ult throughout the game
can be dangerous to silence him late game though if he's ready to stand and fight
That's why you NEVER level BH's silence beyond level 1 until level 23, 24, 25. Always go with something else and stats first. This way, the silence does the MOST damage (dot) and buffs enemy damage the least, and also silences them.
