It's easy, if you follow the setup for that move, your opponent will burst into flames just from the sheer amazingness of it, that's all the explaining that's necessary. It isn't a shovel. It isn't a lift. It is life.
Can't really decide on which opener to choose, since most have a bad side and a good side.
The best one you can use is most likely a snap kick. Takes at most two turns and provides early damage so you aren't scrambling for points later on in the match.
I have a 2 turn opener where i noob clap then throw my weight backwards but still staying on the ground, almost impossible to shovel/snap/lift. but it leaves u off balance.
