1)pick huskar -stay behind enemy creepline and harrass
2)pick bat - stack napalm
3)pick nevermore - outlasthit him and damage him
4)arrange doublemid with decent support (cm,dazzle,wd,lich) and keep him even out of exp range
6)warn your mates if bloodseeker is miss(ward map)
7)just let him win mid and farm his stupid radiance...own him later cos he got no bkb
8)phoenix ,viper , skeleton king, lanaya, invoker, luna,kunka and axe may also have a good time vs blood..but depends on skill ...
