I was thinking entangle for the vaccuum portion of the attack, with attacker+entangle both take damage. So he lines up a nasty shot on the guy with his next phase or two while the enemy is held. However a TK grab would work too. Heck, maybe a CE that imposes huge combat penalties.
Of course, the way I saw the attack working, it's one really powerful hit, followed by the vaccuum. Any followup moves aren't connected to the technique and involve hammering the opponent when he can't fight properly.
