It's all so new and trendy though. How about an old fashioned Liverpool Kiss in the first scrum. Back that up with the old sneaky upper cut from the second row next scrum. Then a few of the tried and tested knuckle massages to the eyeball. Should also resurrect the throat punch, earlobe wrench, nostril block, thumb and finger bends, mouthful of dirt/mud, dencorub facials, fingers up arses, brachial plexus squeeze (deliberate stinger) etc etc and some old exotics like the old bottletop taped to the palm
Quigs told me about this stuff.
