What is the best combo to hit a lvl 10 npc with?

[BarbWrath]

I use 2k war, 2k wor, 4k scouts, 2k trans, 90k archers

With full techs 10 and
Compass 8 - 7-8k losses
Compass 9 - 7-8k losses
Compass 10 - 4.4-5.2k losses

Most effective with compass 10 with 195+ attack hero and ivory horn. However lower attack isnt a problem (Make sure its over 140)

that works best
