For a more general use team (more suitable for defense) you can go with High Khatun-Tormin-Tayrel-Skullcrown. 

Get as much speed as possible with HK, tons of accuracy, speed and def for Tayrel and Tormin, stack crit on Skullcrown. 

HK speed boost- Tayrel decrease def- Tormin Provokes and freezes if opponent manages to squeeze in a speed buff or two, Skullcrown nukes. 



You can also run HK-Martyr-Tormin-Skullcrown

Run goes like this: HK speed boost- Martyr casts counterattack- Tormin provokes- Skullcrown nukes.

With this comp, both Tormin and Skullcrown will both benefit from counterattack with their AoE A1, This comp will be a relatively slower one but will translate to more survivability, more damage and freezes from Tormin, and more hits from Skullcrown. This will only work on offense though as Martyr usually casts provoke first and Tormin does the same so it might be kinda redundant and the counterattack part of the strat might not work. 

Hope this helps.
