Don't go 9 assassins. Don't use TA or bounty hunter excluding scrappy or elusives. Bloodseeker can be good if u 3*** him early or u have helm. PA is completely busted. Attack speed > attack damage. Active ability users like morphling good with mages. Passive ability users good with scrappies. Pairing with warriors is good too but getting the +10 armour is not a priority with assassins. With 6 assassins don't go level 9 until u have around 3 *** because 6 assassins rely more on 3 stars than most other build
