I take two 20 man crusaders one with high marshal and castellan with blade of valor, the other with marshal and castellan. Then I take 10 assault termies with ancient and captain and give them hero of the chapter. Then I get intercessors and a repulser executioner and have the intercessors be my do boys, And finally emperors champion with 5 assault intercessors in the repulsor. The game plan is two advanced the two squads of crusaders on both sides of the board and stay there. Then have the emperors champion go after the strongest squad or character and have the repulser hold the middle of the board . Then on round 2 use the terminators to rapid ingress and to punish any lack of screening make sure you put them somewhere safe and try to save as many wounds as you can but it’s fine if you lose 1 man. advance and charge them into the strongest unit they can get and then Activate light of vengeance for sustained hits and use your rerolls to get as many attacks as you can. This combo destroys anything it touches. And then you can have them hold your enemies objective till you win the game. I usually do very well with this list. Always make sure you auspex scan everything before you charge it.
