There are generally two variations to this comp, one fast and one slow. Both are listed below.

FAST:

This comp allows adding a 4:3 champ into an Unkillable Team.
Unkillable from Turn 1.

257 – Tower
241 – Skullcrusher
240 – DPS moving at 4:3
192 – DPS
191 – DPS

257 and 240 go twice after the Stun, with 257 going last.
Use Tower’s A3 at the start of turn count 1.
Use Skullcrusher’s A2 right rom the start.

SLOW:

This comp allows adding a 4:3 champ into an Unkillable Team.
Unkillable from Turn 5.

240 – Tower
221 – Skullcrusher
220 – DPS moving at 4:3
191 – DPS
171 – DPS

240 and 220 go twice after the stun, 240 goes last.
Use Tower’s A3 right from the start.
Use Skullcrusher’s A2 on turn count 2.

The trick is getting the stun to land on Skullcrusher. He must have SOME HP or the CB won’t target him – easiest way is to give him 1 set of Immortal gear, though it’s possible without by using the Lifedrinker Mastery and having high crit rate and damage.

Affinity Adjustments

Tower/Skullcrusher Affinity Guide

Brief Overview:

Magic (Blue)

• Swap skullcrusher with Bushi

Spirit (Green)

• Use a champ with AOE block debuffs skill on a 3 turn cooldown in the 191 speed slot.

Force (Red)

• Run a magic affinity DPS higher in team order than Tower to pull stun from him.
• Adjust HP/DEF values of magic DPS and Skullcrusher so that eventually Clan Boss will target Skullcrusher for the stun as he is “Killable”.
