I am most impressed that the grappling techniques are almost all legitimate and taught today. I tapped people out with two of those techniques (cross collar choke and arm bar) in the last week as a BJJ practitioner. Same with the throws. The scissor takedown is also known as Kani Basami and is stupid dangerous for the person being taken down. Can easily tear knee ligaments and most gyms do not permit its use in most circumstances. It is effective, though.
