the purpose is to use the capacity of the champion, and to over use it with the cloudshift and the pod.
technically, turn 4, if the champion and the hero fight together, the hero makes the champion +3|+3 each turn. so, in one turn, we have a 4|4, a 3|4 and two 2|2 which are attacking. 4 creatures which cant be blocked by any creature with a force of 4 or lower.
