Deep Strike in 10 TH/SS Terminators, pop Devout Push, walk into combat without suffering Overwatch, force the enemy to stay in combat to stay safe.
There's a lot of interesting shenanigans that can be pulled off that I'd completely overlooked.
EDIT: Actually, couldn't it go like this?
Deep Strike in, Devout Push into combat, kill whatever you blobbed into, get another 6" consolidate into another unit, pop Honour the Chapter, kill that unit dead, get ANOTHER 6" consolidate, move into a third unit and lock it in combat on a 2+ (assuming it's an Infantry unit).
I think I need to go lie down. I can only handle so much Glory at once.
