This is actually very interesting, because this setup could potentially leave your opponent guessing depending on the situation.
What's even more intriguing is the body check. In most cases, you would want to knock away the opponent, but if the D-angle F-Smash connects to a shielding player, it may leave them vulnerable like Marth's shield breaker. If that's what I understand what he means by "devastating."
So in most cases, the body check looks like the best setup. Both a potential shield breaker and a stun punch for combos. This is TOO good.
