Slow Skullcrusher and Tower with 43 Champ
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.
