Right about when they hit the ground floor, Kiryu felt Armed Ninja disappear. Fine. It had stalled the guards long enough. He could set something else up if they tried to follow.

And of course, it didn't look like those guards needed to follow. There were a whole bunch right here, waiting for them. Kiryu quickly started shuffling through the cards still in his hand. He didn't really want to kill these guys--Kaiba didn't need another reason to go after them--so he'd have to go with less hurtful effects.

"Lightning Vortex!" he said, holding out the card. Lightning started raining down out of nowhere, never coming close to himself or Alastair but targeting the bewildered guards with astonishing accuracy. Two were taken down before they could realize what was happening. A couple more managed to dodge the first bolt only to get hit by a second. At least one tried to fire at them but missed by a yard in his distress. But eventually, the lightening stopped and they were all lying on the ground unconscious.
