Fast Skullcrusher and Tower with 43 Champ

BASIC GUIDANCE

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.

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.
